I purchased a computer from Best Buy using my Best Buy credit using a promotional option. The promotion offered 18 months to pay with no interest. The total was not paid by that date. Soon after this period I noticed that the amount owed had jumped by {$280.00}. After contacting Best Buy it was explained that that total included all past interest that had been waived. 

When I made the initial purchase I was not told that the past due interest would be added to any outstanding balance. During that conversation I was told that my e-invoice stated this policy. In order to see this information I would have needed to download my statement, which I had n't done. I paid directly within the " make a payment '' options, or over the phone. 

I have since paid the balance I feel is the amount that I owe. I have also asked my attorney to send a letter explaining the circumstances to Best Buy via certified mail. My attorney 's records show that the letter was received. Best Buy has opted to not respond to the letter.
