Worst Ever car dealings

I have been buying and selling/trading in cars the traditional way for over 20 years. I tried Webuycars and have noting good to say about them. I have not heard from them in a week and their buying office is trying to pressure me into handing in the car that I have provisionally sold to them in order to balance their books when they did not even process my financing properly, I had to do it over via their website.

Webuycars are unprofessional and lazy as when you call the customer care line they give you a million reasons why they cannot give feedback and also give the incorrect numbers of their sales people.
