I was with XXXX for many years, never late, made automated payment every month for all services..XXXX phone company has wrongfully charged me, i have recorded conversation with an agent as a proof..XXXX has overly charged me {$66.00} after the account is closed and without reaching out to me they have sent my account to collection. I could have just paid off enen though it was wrongfully charged..I spoke to XXXX as well as many debt collecting companies for removing these charges but instead these companies keep selling my accounts to new comanpnies and my credits score has gone down from XXXX to XXXX. This is the only debt collection i have in my credit history and this is not fair to consumer ... It 's hurting my credit really bad.
