Synchrony Bank Qvc accct Account Error/Synchrony system/ Orlando Florida

QVC QCard acct is owned by Synchrony Bank.  I have shopped with QVC for many years with no problems.  My particular problem began back in late July, 2017 when my information on my computer was compromised.  I called every account, including QVC, to let them know.  Old acct was closed, new one set up and new account # (QCard) sent.  I let them know my new checking acct # and paid by telephone for several months since my autopay had to be reset online by me and I had no access to a computer at that point.  I purchased a new computer from QVC on August 06. 2017 (advance order to ship on 09-08-2017 and be received by 09-14-2017 - mine did not come until 09-22-2017) The cost of this computer was to be $133.74 per month x 6 months (easy pay).  This was included with the other items already on the account. Ok, everything was fine, bills were paid but the trouble seems to have occurred when the autopay was set up again.  Even though the billing statement said my autopay was to occur on 11-03-2017 $256.27 statement balance, it did not.  Did not know why and I called QVC as soon as I realiized this.  I check my bank account online but did not see the amount to come out of my checking account.  When I called, telephone answered with a recording saying "system down, call back later' and I assumed there had beens a computer glitch.  This was close to a data breach but I don't recall the company named. 

I have worked with systems and did not worry really until I checked my account on 11-09=2017 and saw my account was shown as late.  Tfhis is when the telephone calls began with me calling the number on the statement and talking to a different person each time; Seemed like some understood my problem, others didn't.  They would tell me there was documentation where I had called before but I am not sure how thorough it was.  I have written down each day I called, the number called, who I spoke with, etc.  This went on into December with me trying to find out what was happening.  I finally figured out that the payments weren't being deducted.  I was told to go into the account and check the checking account number and change it even if it was the same number.) ) What was shown was my old checking account number ending in 5224.  New one ended in 5011 (same bank).  SO what had happened was my QVC Qcard was accessing information that had not been current since late July, 2017 even though I had told my new account when I got it..also in late July.  I took the advice of the person who told me to put the correct number in, which I did, considered all ok.  Still didn't solve the problem..I kept pulling up the account, seeing incorrect information, becoming upset. 

At one point I went back in and the SAME OLD CHECKING ACCOUNT NUMBER ENDING IN 5224 was shown.  I changed it again.  I called, told I had obviously entered the old checking acct # , which was infuriating, becaused, as I explained, I didn't even have that number to enter since I had thrown all that info away when I got the new account.  Seemed like things were on track to finally be straightened out...but no.  Synchrony Bank closed my bank effective 12/01/2017 and I had no idea except I had pulled up the account again and saw a statement on there that the account was closed. I received a letter from Synchrony dated 12/08/2017 saying the account was closed and it always takes about a week for a letter from them to reach me.  There is more and believe it or not, this is the short version.  I guess the last straw was the letter I got from Synchrony dated 01/10/2018 and received 01/22/2018.  I was really too mad to call the numbers given, and still too mad to call today.  I am very upset and hurt also by the treatment from Synchrony.  I have quite a collection of paperwork...statements, all letters.  I hope this helps.  Thanks.
