<prompt> Human: Bought a TV for 1000 in 2012.. they offered me 24 months, interest free! Awesome! Got my BB credit statement in the mail today.. 470 interest charged?!! WTF!I have been making monthly payments of over 75mth.. for 24 months.. surely that shouldve taken care of that TV right?Called them up... turns out UNLESS you specify which purchases you want your payments to pay off, they will, by default, pay down the highest interest rate products aka not the interest deferred items. So all of the smaller items head phones, speakers, etc. were paid off using my payments, even though they were purchased a year or more after the TV.Thus, I am left with a hefty interest fee. I must have signed on some agreement which is my own fault for not understanding the rules, but wow, this was a shocker. Just wanted to post this story so I may help someone avoid a similar situation.Buyer beware!  <response>: Im pretty sure this is EXACTLY why they offer this.
