TEMPO LLC/ WHY NOT LEASE IT? Supposed to be a 6 payment same as cash method, then you find out you're going to pay twice the amount+ $600 to $1,200 Manchester NH

So I went to Sears to look at some appliances and needed a washer and dryer. Found the washer and dryer that I wanted and I had cash in hand when the customer service sales person tells me this great program that they offer with a company called whynotleaseit. It's great she says six payments same as cash plus a $200 payment for the loan after your 6 payments are made. Well I made my six payments and was expecting to make this final payment when I call to make the payment they proceeded to tell me it's going to be $600.

Well no I said unacceptable this was not what was discussed upon purchase. That's when the jargon started about how they were just going to recycle this 6 months same as cash payment so that I can continue to pay another 6 months worth of payments and finally a $600 payment which would ultimately be a $1,200 payment because it was late. Oh and after all this I've already dropped $3,600 and they tell me I don't own it. Now they're affecting my credit score. Where's the justice? I have stopped my bank from paying them and as far as I'm concerned I own the washer and dryer. Shame on Sears for even being affiliated with this company.
