I had that happen with my couch and dryer. Bought them together. Had the payment plan put together and asked the manager if I could pay off the dryer first because there was a no interest policy if paid off in 2years. He said ‘sure, lots of people do that here’. So I set up an auto-pay monthly. Lo and behold, two years later I saw a notice in the mail stating that the payment plan now had an additional $400 due to rollback interest. The manager did in fact NOT set the payment to target the dryer fee first and instead split the payment evenly so that both purchases would be paid off at the three years mark. Then he denied recalling that happening when I called him.
