08000641087

I'm still recovering from a quadruple heart bypass and these clowns seem to call when I am resting.or trying to get a couple of hours sleep...I reject the call as I do not like time wasters.

I've had this phone for a while and this is the first time they have called, i don't answer unknown numbers at all.

add the number to your contacts as fool, twit or what ever then when they ring you will know its just marketing and hang up rather then wondering who it was

Im on giff gaff and was called by this 0800 064 1087
Multiple times. Obviously giffgaff is run by o2 so this would make sense....

I received a call from this number yet again. I didn't answer but did a search on goggle to find out who it is.  Turns out it's O2.  I have never been with O2 and never will.

I have just today found Telephone Preference Service and registered my three numbers with them to stop nuisance calls, it will take 28 days to completely stop but if it doesn't then you can either email them direct or there is an address to contact as this is ILLEGAL

Scammers - should not be allowed.

After reading the majority of these comments I personally feel I need to defend the people that are doing this 'cold calling' for a living, myself included. Not one of the numbers that are dialed are personal, we don't look up a number and type them in to harass you. We work off a database which dials numbers every 30 seconds under no control of ourselves, unless we pause to break. It also  gives us the option to disposition a call to however it ended. If you don't answer we disposition it as 'answer machine' therefore making it recycle round to be called again by someone else in the call centre. If you answer the phone and say politely to have your number removed, there is an option to have the number suppressed from future calling.

I am a young girl just finding my way in the world and this is the only job I could get in the current climate that feeds me and my daughter and keeps a roof over my head. I'm not sure what everyone does for a living, but I'm pretty sure that if you were told to f*** off on a daily basis you would be a bit peeved also.

We are told by our superiors to 'objection handle'. Example: I'm busy - I understand that but I will only keep you 2 minutes'
All calls are recorded, if we are not seen to be doing this we can lose our job and end up on job seekers.

All I ask is to not answer the call guns blazing and abuse the adviser because they are human beings too.

And yes we are calling on behalf of O2, the company itself buys data from clients which are O2, giff gaff, Vodafone, t mobile, tesco, Virgin, ee/orange etc. maybe you should contact your actual provider and see if you can suppress your number from being passed on.

I can't speak for the rest of the advisers in the business but I ask questions to the customer genuinely trying to see if I can save them money, not to con people! If I cant do a better deal, I let the customer go.

Also in regards to data protection, if you are on O2 we have a separate web page to enter the mobile number into to see whether you are with O2, it has details such as name, address, whether you are contract or payg, and how much you are using. For data protection purposes we am have to ask for full name and postcode before we discuss any of the details in the account because we could be speaking to anyone also. If we phoned someone and started talking about your account without asking to confirm you wouldn't be too happy, so it initially for the customers benefit. And I wouldn't risk loosing my job just to prove I am who I say I am, because there really is no way to prove unless you confirm details.

I apologise for going on a bit but I hope this will give you all an insight f how it is on the other end of the phone.

somebody call me from that number

rang up o2 yesterday to order a new contract, changed my mind and havent taking it further.. been greeted with two missed calls from this number today. afraid to ring back due to cost.

0800 641087 keeps calling

Keep getting calls from this number. Finally answered it to find it was from O2. Hung up straight away since I don't want any unsolicited marketing calls from a mobile network I have no association with. I've been with Vodafone for years. At least I can add the number to my reject list.

Have had 8 missed calls in 5 days. Not impressed.

Then tell them what times you're going to have a rest and ask them to call another time!!!!

For chrissake!!!!!!

Or tell your current network provider and they can block the number for you. Happened to me to. Lol

Keep gettin calls from this number like 5 or 6  times a day

I missed the call and rang back, the automated message said it was a call on behalf of O2, but not who actually made the call.

3 missed calls and it is not a call i should be recieving. think its an absolute disgrace that o2 just give numbers out

I just had one of these at 11 oclock at night

I answered the call to a guy called Steve who claimed to be from O2 and was wondering how my handset was. Then he asked what handset i was using, if i had a contract with O2 etc. I responded with "If you are from O2 you will know all these answers before i have answered them!" When he saifd i was due for an upgrade i knew he wasn't from O2 and promptly hung up as i have just upgraded 2 months ago!!

They claim to be from my current network provider so how would that work? Block themselves?
