I recently made payment arangements with MCM to pay off a T Mobile bill. They constantly blew up my phone and didn't leave a message each time they called. I finally reached someone and asked them why they were so persistent in attempting to reach me at least 15 times a day. They never left a voicemail but instead, called over and over again. In short, if i don't recognize the number, I'm not going to answer the phone!! I finally amde the first of two payments to close off the debt and asked "Sean Jackson" if they were indeed based in San Diego.
