Synchrony Bank Credit Card Complaint

Synchrony Bank Credit card department,

Billing statement Texas

I purchased hardwood floors from - -/-/-. I have no idea what the account number is no nothing. I have been paying and all I owed was $1100.00. Well my -/-/- statement tacked on $710.00. I was devastated! Well I tried to pay it off using my - credit card and they would not allow me to do so and that they could only use my checking account. If I do n't have the extra money and I consider this credit card fraud. How would be able to pay it off with the extreme interest rate which does n't show on my statement nor does the account number. They are really using shady tactics and need to be stopped. I have never experienced anything like this before. Thanks for any help you can provide. I 'm - and simply ca n't afford the extra.
