I was given a credit card application in a Best Buy store XX/XX/XXXX. I used that card to purchase a laptop and a few other small items. I was told my card had a limit of {$1500.00}. I was not told anything else and I did not use this card ever again. I was never told there was any promotion tied to the account. When I logged into pay my bill, I noticed that last month my balance went from approximately {$500.00} to over {$1000.00}. This was solely due to a deferred interest charge and attendant finance charges. 

No one from Best Buy ever told me that I was accruing interest or that I needed to pay-off my balance in full by XX/XX/XXXX. If they had, I would have done so. When I called to complain, a Best Buy representative told me this was a common complaint, particularly for customers who were enrolled in paperless statements and he understood why I was misled. He attempted to override the imposition of the interest charges but was unable to do so because of Best Buy corporate policy ( according to this representative ). 

I find it extremely deceptive and abusive to provide no disclosures about the terms of a credit card during holiday shopping season and then, nearly two full years later, apply a 100 % increase to my balance through a deferred finance charge. Had I been told I needed to pay-off my balance in full, I would have done so immediately and avoided this {$500.00} charge.
