I went to Sears XXXX in XXXX 2013 to get XXXX for my son. They said if I put the amount due XXXX {$3400.00} XXXX on my Sears Card it would be interest free for two years. I already had a balance on my Sears Card, and I was making monthly payments. I just received my Sears Statement today and while the balance was {$4900.00} last month, it is now {$7100.00}. A charge of {$2300.00} representing interest was charged to the account. If the original amount for the service is {$3400.00}, how do you get {$2300.00} in interest after two years? This does not make sense.That is a 69 % interest rate. Is that legal?
