I bought a bed using an interest XXXX credit card. 
I had used the card for purchases in the past, but paid them off after realizing I had been mixing up my cards ( statements attached for XX/XX/XXXX ). 
In XX/XX/XXXX, I used an XXXX, forgetting this card was still linked to my XXXX account. 
Realizing my error, I paid off the uber charges immediately. The charges did n't fall off the account, despite payments made. I made several payments, but was charged an interest fee ( XX/XX/XXXX and XX/XX/XXXX Statement attached ). 

I contacted the bank ( Wells Fargo National Bank ) and was told I needed to make all payments within a XXXX day window, so payments made before that window are ignored. I spoke with an employee and a supervisor.
