Extremely unhappy

I am extremely disappointed with the service that I have received from We Buy Cars Midstream. I bought a vehicle outright in cash, so naturally I expected a smooth, professional process. Instead, when I went to collect the documents, I was told that they only provide copies, not originals, which was never properly explained. My simple request was to have the invoice changed into my father's name so he could register the car directly in his name, avoiding unnecessary costs and delays. Instead, I was passed from the sales team to admin to the sales manager, then to a supervisor, each giving different answers. The sales manager initially said the invoice could be amended, but the supervisor later flatly said he couldn't promise anything. I was promised feedback on Tuesday; no one contacted me. I followed up, I called the branch, I asked for help, and eventually I was given an email address for the sales manager. I wrote on Tuesday and still haven't had the courtesy of a response. This level of communication is unacceptable, particularly when I paid in full. My concern is not only the refusal to assist, but the runaround, the contradictory information, and the total lack of follow-up. I expected transparency and basic customer care, and I got neither. I hope We Buy Cars addresses this and treats customers more respectfully in the future. And u am expecting them to give me feed back regarding this.
