So we bought a mattress, the sales clerk ordered the wrong one. I called and asked them to switch it to the correct one. Which they did. Now for the ethical dilemma, I opened a credit card to purchase it (because they were going to give me a discount on the mattress). This was like 4 months ago, and I have gotten 2 credit card bills both which show a CREDIT of $500, which is not how much the mattress was supposed to cost, I have no idea where that number came from. What do I do? I don't want to rip the store off, but I am worried that if I try to call them somehow they will end up charging me double or something after I sit on hold for who knows how long. And honestly I don't even know who to call, credit card? store? What do you think?
