Poor Service (Procedures/documentation) and after sales service

Company bought 2 vehicles (VW Caddy and Mahindra Mhawk) from the Springfield branch on 4th April 2024. The service from the salesperson, Marc, was excellent. To buy a vehicle from Webuycars through a company name is a nightmare, took us more than a month to get the final documentation finalised. The VW Caddy had an engine problem (electrical & injectors) and there was delay in the registration and collection of the 2 vehicles. On collection, the VW, had a breakdown, and still after 3 months, we have not taken the vehicle in possession. The licencing process and procedure are of a poor quality, as while we were waiting for the VW to be repaired the COR on the Mahindra expired. We had to redo the COR, but the Mahindra failed the test. How did it pass the first COR by Webuycars in April? Now it is July, and we are still stuck with extended warranties and claims to get the 2 vehicles issues resolved.
