Terrible assistance

I need assistance as I have purchased a vehicle from webuycars 5 days ago on the 3rd of complaining to we buy cars about faults that were not advised on the dekra report or disclosed to me directly, they log a case after which I was advised to get a quotation done on the vehicle, I couldn't move the vehicle from my yard and risk being stuck on the road so I paid a rmi mechanic to come through and assess, which I was then advised the vehicle needs to be towed stripped and assessed, I've asked webuy cars to cover the cost which the refuse to do so, and now wants to put me in a jam, I can't have this, they need to take the vehicle to there dealership Springfield which it was purchased from for further assessment, and the best part about the dekra report it stated the vehicle lights wiring is burning which is not, so you can see how much lies they speak
