Who called from 7087460373

I received multiple phone calls recently, I answered once because 708 is local to me. The guy said he was from XM Radio. I asked to be removed from the list and he asked to confirm my phone number so I hung up. He just called ME, shouldn't he have my number? Probably a partially automated call system.

This # calls every day and it is XM Radio.  Wish they would stop calling  told them im not interested.
