<prompt> Human: Hi Reddit,I bought a mattress from a local mattress reseller I found on Facebook. His operation looks like a one-man set up - I connected with him via his advertisement on Facebook. He says he shows the mattresses by appointment only to keep costs low, and so I make an appointment to go pick a mattress. When I show up, he has a showcase room with about 20 mattresses set up. I lay on a few, and settle on a tempur-pedic mattress that he wants to sell me for 400, plus a platform bed frame for an additional 100. We agree that he will deliver it to my house the next day for 20 delivery charge . He comes the next day with two large boxes, one with a rolled-up mattress and another with the frame. I didnt expect any funny business, so I pay with my card before opening the boxes. The next day, I open the mattress box and discover that the mattress is not the same that I tested in the showroom, but instead a cheap Classic Brand memory foam mattress that looks similar but feels very different. I think I have been the victim of a bait-and-switch scam. I contacted him immediately and left a message on his phone to inform him of the mistake. He hasnt responded.What is my next step? Can I use a charge back if he does not respond?Thanks,x200B;x200B;x200B;  <response>: Yep. This sure seems like a scam. Contact your credit card company immediately.
