<prompt> Human: Last year I bought some appliances from Best Buy using their credit card, it was about 1300 total. They had a promotion going on, 0 interest for 18 months. The first few months I was paying the minimum due, which was around 30month. After not noticing my principal going down, i upped the payments to 250month. I will have this paid off completely by next month, however, if I pay them what they say is due, I will have paid them 1400 in 12 months. Their promotion was 0 percent interest if paid in 18 months. I paid them every month, just didnt understand the minimum payment was the minimum they would accept before they repot your shit. Do i have an argument that I should pay them a total of 1300, not the 1400 they want me to pay? Edit: here is a link to the promotion Assistant: No. You didnt understand how the promotion worked.Human: please enlighten me, as a red blooded american foolish, I know, i take things at face value, not thinking there are an army of lawyers doctoring everything up for corporate America to justify their rat like existence.  <response>: Get the fine print out and read it. There was probably some stupid ass fee for something you didnt know about. Credit cards from stores are the most horrible kind because of this shit.
