I obtained a Sears MasterCard on XXXX/XXXX/15 when I purchased a treadmill at Sears. The treadmill charge was interest free for XXXX year if paid in full in 1 year - it is called a promotional balance. My statement closing date was XXXX/XXXX/15 and my payment due date was XXXX/XXXX/15 the total balance owing was {$610.00}. On XXXX/XXXX/15 I made an online payment of {$620.00} paying the entire promotional balance in full. During the period XXXX/XXXX/15 thru XXXX/XXXX/15 ( my second statement closing date ) I charged XXXX auto repair charges which were reflected on my XXXX/XXXX/15 statement. When the credit card company received my XXXX/XXXX/15 payment they applied noting to the promotional balance of {$610.00}, which was also the total balance owing on that statement, but instead applied the {$620.00} to the charges that were made after the XXXX/XXXX/15 statement closing date. I requested that the entire {$620.00} be applied to the promotional balance, therefore, avoiding any interest being applied to that amount., but they have not agreed to do that. I feel this is a mis-application of my {$620.00} payment and I would like this corrected.
