Synchrony Bank has been non-responsive and lied to me about the status of my billing disputes. They sent me a letter that is dated XXXX XXXX, XXXX stating my account will be credited {$3700.00}, but these credits never posted to my account. Also, this is not the full amount under dispute, which is {$7000.00} for XXXX transactions. I called on XX/XX/XXXX and XX/XX/XXXX. Each time they confirmed the dispute ( s ) were resolved in my favor, the correct amount of {$7000.00}, and these credits will be applied to my account, which never happened. I called on XX/XX/XXXX and was informed there are no credits pending and there is no record of this letter I received on XXXX XXXX. They requested me to fax the letter to them, which I did with a cover letter and have not received a response. 
Previous history : The first letter I sent was on XXXX XXXX, XXXX regarding disputing transactions from XXXX to XXXX. Synchrony acknowledged receipt of my letter on XXXX XXXX. I called in XXXX and was informed I 'll receive resolution letter within 30 days. I received nothing, so sent a second letter on XXXX XXXX, XXXX. Once again, I received written acknowledgement on XXXX XXXX, same generic response as XXXX XXXX. Then my next communication was the XXXX XXXX letter. None of this is following the dispute process outlined under federal law.
