Just got this call - asked for the property owner, when asked who was calling they said "a company, I'll call back" then hung up.
I was a Team Leader in a Call Centre, this guy was reading from a script and new to this job.
I'm on everything that restricts my number, never give out my number as a contact - I have a mobile that sits in the hall - when this goes off me and the kids know it's probably a call centre, we're never the "property owner" - we usually say it's a 'council house' - and we're never give date of births or bank numbers over the phone. (unless we call them - bank and utilities)
we make one chargeable call per month, usually to the answering machine.... they still leave messages!!!!
The great thing is we switch the phone off when we want peace! Fantastic!
I'm sure it's double glazing
