I purchased gas on 8/9/20 with a credit card. Cashier told me if I didn't pump full amount, she would apply a credit to the card. I asked her if I need to report back to her. She said I did not. After checking my account today, the original $30 charge was posted to my account. My purchase totaled $19 and some change. The balance of $10.xx was not credited to my account and is not listed as pending.
A credit of $10.xx is due to me and the receipt is attached for your reference.
