<prompt> Human: Had a company come out for an estimate. I signed what I believed to be a trip fee as the company was not able to do anything to help with my issue. there was no prices listed anywhere on what I signed. A few weeks later I get an invoice with charges for services that were never done. I tried to call and dispute this with the company. They would not change the charges and are threatening to send to collections if I dont pay. How should I deal with this? Ive written a bad review and even contacted the BBB and consumer protection but the company will not budge. I know you can dispute things with your credit reports if it gets that far but how would I do so successfully? Is there anything else I can do in the meantime?  <response>: Refute in writing. If the sent to collections, send a new letter plus the old one to collections. If sent to a credit bureau, send both dispute letters.
