Debt. Collector

Debt collectors have been repeatedly calling me and asking if [name] is available. I say no and they say they'll stop calling. They continue with different numbers. This specific number is a robot dialer with a British accent. I live in the US.

This is another number that so-called debt collector Convergenrt outsourcing uses, they use different numbers everytime and I keep blocking them. They ask for a Ryan Krotz and I've never heard of him. I think its a made-up name to get more information about me. I've told them not to call and they continue. Really pissed off. One of the otther numbers is 6613160253 if you see it block it, don't answer.

Convergent Outsourcing, Inc. called and knew my name but asked for my social which I declined to provide and then he said bye and hung up.  How about I call you and say hi i'm collecting on a bill is your name "John Doe" oh yeah? Can you give me your social? .... SMDH.

this number just called me 6 times in a row....no message, just air.
blocked now...no idea why they would be calling
