Have not received my registration documents for my car

I bought my car at webuycard Midstream branch in November 2022 , I paid cash for it but still today I have not received my registration documents. I first called your customer care in December and they said they are there and when we got to the branch they could not find. They gave is the extension of disc because it os now expired. My husband communicate with the sales man that was assisting Jacob and he says that the documents of this car are at the finance department and still not changed. I called today and the lady ask for the my I'd number and the car registration and she says she can't pick up my details. What is really happening? I am not happy, please and I need the documents of the car with my name, I have waited enough now.
