<prompt> Human: First time post, so cut me some slack lol. On May 18th I had a new AC unit installed in my home. The company wouldnt finance me so I got a 3rd party lender. I had to pay the AC company for 875, to cover the difference from loan. However I got a call today from the AC company, saying they never withdrew the 875 and asked me to verify it was not withdrawn from my account so they could run my debt card for the 875.Now, 3 months later, I dont have the 875 anymore to make this payment and I dont know what I can do. Has anyone been in this situation before that can help? Or anyone with and suggestions would be much appreciated.  <response>: If you agree to pay someone, you have to pay them. Payment errors dont change that.You need to tell them you dont have it and work out an arrangement with them asap. Otherwise, theyre going to put a lien on your house, which you really dont want.
