Product: Credit card

I have been trying to appeal to this bank over the last couple of months to no avail. In XXXX through XXXX three of our major appliances broke down. Our range in XXXX, our refrigerator in XXXX and then our dryer in XXXX. We had two PC Richard credit cards between the two of us only one at the time was active, carried a modest balance and was in good standing. 
Our card with the largest balance currently is our account ending in XXXX. Our balance was only {$730.00} as of my XXXX statement. Now its over {$2300.00}! We seen this coming and as already mentioned, attempted to work with this bank as they were getting ready to charge us over XXXX in interest if the amount of {$730.00} was not paid off by XX/XX/XXXX, which already passed. Keep in mind we have four cards with Synchrony bank. Two, PC Richard cards, a Care Credit card and a home Design card that is almost satisfied. They are all in good standing and we are paying our bills on time with automatic payments every month. Our Care Credit card we are especially careful with as we need it for veterinary care. it has a balance of over XXXX we are struggling to pay down all from veterinary bills over the last three years. 
When we contacted this bank online in regard to this account, I stated, " I regret to see this response. I can assure you if I am charged interest of over {$1200.00} next month, I will be forced to close the account and take my account off of automatic payments. I can not afford to pay all this interest and or have a min payment double or triple as a result of this. It is already passed XX/XX/XXXX. I really hope that this bank will reconsider this stance. I will make my min payment this month and hope this can be resolved in some way. '' To this, I received an answer of " ... ... ..Please be advised that your account balance consists of both promotional and non-promotional balance. You may avoid interest on any non-deferred purchases by adding the amount of New/ Non-promotional Purchases to the Minimum Required Payment from your statement and sending that amount as payment. As of today 's date, your non-promotional balance is {$790.00}, on which interest charges are still applicable. You may avoid interest on your account by paying the entire billed balance by your due date. '' This is their response? We had a very recent hardship in which we have a leak from our upstairs bathroom from a bathroom renovation job that was done six years ago. we just learned we are going to have to replace the entire shower floor. This is going to cost us at least XXXX. We are getting estimates now and can prove this. We also had a hardship this time last year, as we were involved in a hit and run accident and our long time insurance company would not pay the claim. We had to sue them in civil court and although they settled, we were still out over {$1200.00} in rental car and DMV penalty fees as a result of this incident which got us in debt on a credit card. 
Taking all of the above in consideration, if this bank can not work with us on this, then I don't know what I am going to do. I am going to be forced to propose a settlement. We tried to make a couple of extra payments recently, doubling the min payment but it didn't help much. it as all we could do.
