after they got me to say "YES" they said perfect.. and hungup

Said they were Orthopedic -something. Knew my first name.  Wanted to know if I was the one who suffered from back or knee pain.  I kept asking who they were calling for.  They kept asking the same question.  Finally I answered YES - who are you and the woman said PERFECT and hung up.  After I hug up I remembered something about a scam where the caller got you to say YES and then they injected that into another tape or something.  I normally don't even answer when I don't know who is calling but this was early in the morning, my br was too dark to look at caller id and I was dumb enuf to answer.  It said Moravia CA I saw afterwards. I don't remember the rest of this scam and it may be too late but if anyone can tell me ... should I put some kind of alert at my bank?  Notify the police so they have a record?  Any ideas?  Don't know what context they will put my YES into.  Can anyone help me?  Do I need to change any cc nos? etc.  They did not ask for any financial info but they did have my phone no. and first name.

I have heard about how scammers use tactics, like getting you to speak to obtain only the words they could potentially use for their gain if at all successful. Including getting a simple yes and hung up as they did to you. It is crazy how these scammers are getting more creative in victimizing people. Hope all goes well for you and whoever the caller is, that it doesn't work out in their favorite.

Message was inaudible at the beginning who they were or what company they were from and then it proceeded with a message that in 24 hours I would be taken into custody by local cops four serious allegations pressed against my name. Is this some kind is scam to get information?

The whole idea is ludicrous. How are THEY going to prove who said one single word - "Yes" to anything? Just getting your voice recorded is not a legitimate way to charge you money, especially when they don't have your financial information. Having a first name and your telephone number isn't anything, and it's certainly not enough to take money out of a bank account to which they have no access, likewise any credit card information. I'm pretty sure that by now, this "Yes" business is as much of a scam on them as what they tried to perpetrate on others.
If these ghouls could put all this creativity into something legitimate, instead of all this criminal terrorism, we might be living in a better world for everyone.  (Yes, I said terrorism, that's not a typo. They are trying to force money from people by scamming, lying, and frightening them, threatening them with court prosecution, arrest, etc., - to me, that's just as much terrorism as using a gun.)

They did it to me to I need help with getting them to stop

Since you did post the phone number of the caller, your post is of no use to anyone.

The "Say Yes" calls are not scams. This has been debunked for years. You may be confirming that you have a working number and get more calls, but this is about it. If you are worried, set up credit monitoring for your peace of mind.

Tonya, you may wish to consider diverting all unknown calls to voicemail,
but remember that this will also prevent healthcare professionals from getting through, they were a target for scams, so don't give out their numbers publicly.
You should do the same, maybe prefix outgoing calls to untrusted with the "hide number" code.

Mobile, settings to ignore calls not in Contacts.

If it is a landline, ask about your service provider activating call screening.
Or get a "Call Screening" handset, if they will charge you (they shouldn't, the problem is their end).
