Have I been ****med by Webuycars?!

I Purchased a car via the online auction on 29 July 2022, I paid payment the same day and awaited a call from a salesperson to assist with finalising the deal. No call was received so I contacted the call centre and was provided with a number for the salesperson who was supposed to contact me. After initiating contact with him, he sent me an email requesting the necessary documents which were provided, He then sent me blank documents requesting to sing them which I refused as these are to my knowledge legally binding documents. After a week of refusing to sign a blank document and reporting a complaint New Concern: 25427. email was received with completed documents , These documents were signed and sent back, no response was received. Due to being in contact with customer care agent and having him put pressure on salesperson eventually a response was received from salesperson with quotation to transport vehicle. Quotation provided on 10 august and Payment was made on the 11 August for the vehicle to be transported. 1 week later 17 August and the vehicle still hasn't been transported nor was in transit. Upon requesting a reason for the delay no response was received from the salesperson until now. The Salesperson and customer care agent have ignored all mails since 18 August. A new complaint was logged on 23 August New Concern: 26315 and no one has contacted me or provided any feedback until today. I would like to be refunded for both the car and transport fees
