<prompt> Human: I have another username that I typically use, but I try not to use it for serious posts. Long story short here: Last week we called and got someone to fix our natural gas unit that wasnt producing heat. He came out, did some things and said it would be fixed. Well, its not. It does blow out air now which it didnt before but its cold air, and it doesnt come close to actually heating the house, of course. He also wired the fan to where it stays on constantly. Meaning, it will not work on auto and stays on 247 unless we manually turn it off. My SO tried called and explaining: they hung up on him. Its an actual business, not some bullshit one-person from Craigslists. Its just a lot of money for something that isnt fixed when it was supposed to be. I was thinking about disputing it with my Credit card company Capitol one Does anyone think this is a good idea? Or are we just most likely SOL? Thank you for your time.  <response>: If they billed you for repairing it when it was never repaired, thats a good sort of charge to contest, sure.
