Who called from 9712643753

This number is driving me nuts!!! I am being accused of cheating on my spouse because of this person or company! I would like to find out who and why they are calling me 5x a day. I feel like this is harassment and they should be sued. They never answer when called back and out of the hundred missed calls they have left no message!!????? For some stupid reason I can never answer a call from them?? I always see a missed call but my phone doesn't ring. They call all hours of the day - even past midnight....I WANT TO KNOW WHO THIS SOB is!!!!

I keep getting these calls, however, I do not answer them and will not!!!!!!

I keep getting this call, however, I do not answer it!  I also get one from 000-000-0000.  HOW ABOUT THAT!!!!!!

I called it back and its from the medicare help center.

I received a call from this number today.  When I answered the caller said "Hello this is Joe, I understand you were inquiring about your Social Security Disability" I said I don't know what you are talking about and hung up.
