Complaint Review: Fifth Third Bank

I opened a credit card account with fifth third and as per agreement i have kept my card up in good standing on time and everything as per agreement on my end, fifth third raised my interest rate to default amount because they felt even though i have several accounts in excellent standing, my medical bills which are in dispute over mis treatment/diagnosis, and which are auomatically turned over to collections in ohio are enough to raise my amount to the highest interest rate there is which on my agreement is reserved for repetitive late payers and rubber check writers. this interest rate is about 8% higher than the maximum under my card member agreement.
