This year in March we added 3 extra days to our usual week, 1 on the front and 2 on the back. I paid for the first day when we checked out of the room and have the receipt. At the end of the stay I paid the residuals for our week and the final two days and have a receipt showing a zero balance. When we got home, there were three charges on my accounts. They had charged me for all 3 days before we even got there without my authorization. They had used the card number I was required to give them to hold the reservations. The other 2 charges were the ones above that I paid during the stay. I called the credit card company and disputed the 3 day charge and they agreed with me and removed the charge. The resort says I still owe them the 3 day charge. I have sent them the copies of the receipts showing that I have paid and there was a zero balance. Nowhere on the receipts does it list a credit for the 3 day charge, but they still insist I owe it to them. They are holding next year's reservation hostage and say I will still have to pay the maintenance fee even though they won't let me stay until I pay. What can I do? I refuse to pay them twice for the rooms, I don't have that extra money laying around!
