If you owe on an old credit card, then your on the call list of all involved of collecting. They want you to volunteer information, basically verfying for them that you know you owe for that credit.
It is a tricky way for you to admit that you owe on what they already know.
No matter how many times you change your number, your phone service sells out your information to all kinds of businesses and agencies.
I say either pay your debt or just ignore their calls.
This same number called a short ago on my cellphone. I didn't recognize the number and ignored the call. No message left of course. Per previous entries it appears to be scammers trying to rip us off.
Received a call on my cell from this phone number at 12:25 PM Eastern Time on 9/27/2014. I ignored the call and they did not leave a message. Probably someone trying to scam and attempt to rip off! Scammers are IDIOTS!!!!!
