I got a collection notice in the mail from Afni, for a tmobile bill I paid over 6+ years ago. They can't give me any information on where the bill has been for the last 6 years and my ex and I paid if after going our separate ways in late 2017. If this company calls you give them no information they don't already have and verify nothing with them, that's how they get you! Someone needs to do something about this company and the companies that sell them this bogus information. They are selling old customer information to afni and afni is banking you you caring enough about your credit that you will just pay it.
