Who called from 8104061984

Called multiple times with either UPS or Flint MI on caller ID but leave no message.
I also received a call with caller ID with my own number. Time to change my number.
So tired of paying for a phone where these companies get my number for harassment. This is my fax number so there should be no calls coming in only fax.

Yup they called me and hung up. I have only gotten one call, but they sound like a fake company.
