<prompt> Human: I made a 2,000 purchase with my American Express Gold card. It was listed as pending for 2 weeks, then it disappeared without posting. It has now been 2 weeks since it disappeared. Ive heard of charges disappearing for a day or two, but not this long. I doubt Im so lucky that someone made a 2,000 error in my favor. But in case thats what happened, Im hesitant to contact the payee Roto Rooter. The other wrinkle is that I was hoping to trigger a sign up bonus with this payment, and to make this happen the payment would need to post within the next 2 months.Any thoughts on this?  <response>: Contact the company. You agreed to pay that sum, so they can charge it or send it to collections at any time. They may not discover the mistake until the end of the quarter or year. Contact them sooner then later do you get your sign up bonus charge.
