Arrogant and Non Delivering service provider

In an average world it takes a day to purchase a vehicle, been trying to buy a car at Sandton Repocars for three weeks, all issues with the vehicle where not fixed, manager or Owner also arrogant enough to ask me what wrong with me when I wanted to cancel the deal, goes as far as telling me not no waste his time if the deal isn't going to happen. I don't know how they are in the motor industry with such disgusting service and would wish to know where to go to put an end to such. When you try to purchase a vehicle and you are treated like they are doing you a favour. Disgusting and appalling.
