WeBuyCars Poor After Service

I bought a vehicle from We Buy Cars Silverlakes on Thursday 19/04/2018 and on Friday 20/04/2018 the vehicle left me along the road in Centurion, We Buy Cars Silverlakes said they will see if they will be able to help to get the vehicle to VW Centurion, after standing next to the road for almost an hour I had to arrange by my self with VW Centurion to send a Pick up truck. Spoke to Gert at We Buy Cars Silverlakes after VW Centurion said that the vehicle will have to stay there till next week, they need to order the part from PE which caused the vehicle to break down, the part will only be at VW Centurion on Wednesday 25/04/2018, the vehicle is not even one day with us, mean while our Business is standing still and we are losing money every day that we don't have a vehicle, as We Buy Cars doesn't have loan vehicles for Clients in need when their vehicle breaks down. Gert just said that they don't give loans vehicles because their vehicles on the floor is not insured, just one question "so if your clients test drive a car at We Buy Cars and someone drive into such person, We Buy Cars is not insured? Mean while me as the client that signed a contract that you are so eager to sell a vehicle to, vehicle broke down and is with out a vehicle, you as We Buy Cars don't give a Dime, your after service is to the dumps, I would appreciate it if someone could contact, i'm the client and you should keep the client happy. You sell a vehicle to a client and the next day the vehicle is leaving me next to the road well I would really think that you would be there when the client needs you the most. I would like to know why do they put additional Charges on my contract without notifying me first, Innovation Bodyline Maintenance and Netstar Vehicle Tracker, which is not a must according to the bank.
