On XXXX XXXX, 2015 I mailed a certified letter to Financial Data Systems requesting a cease of communication notice. The return receipt was signed on XXXX/XXXX/15 by a XXXX XXXX XXXX. I received multiple calls after the letter was signed for. 
I also explained to the credit agency that I have not missed a payment, nor was I late EVER with a payment to their client. When I reported that to them, they claim their client is proceeding with collections even though I 'm not in default in any way to our existing payment agreement. 
And there were fees in the amount of {$370.00} additional added to the balance of {$1500.00} I owe their client. They can not justify the additional charges.
