purchase of storage shed on a rent to own. I was told no finance charge. When I recieved my payment coupons I toled up the amount it was cost for shed at 36 month's. $2563.00 @ $125.60 per mo. That would make my purchase go to $4521.60 total. That is almost double the orginal amount. I paid it off today June 28, 2017 and they tell me it will take about 8 weeks to get my paid contract back from them. I feel that is much to long when they are paid in full. What can I do?
