WE BUY CARS WORST AFTER SALES SERVICE

I bought a vehicle from We buy cars website on the 10th of february from Richmond branch and the salesman contacted me and we finalised the paperwork and also sent me an invoice for the delivery fee to their Pietermaritzburg branch which is nearer to me. Today is the 23rd of february and still the vehicle has not been delivered. My question is why allow sales to customers from other provinces when you cant deliver? The saddest part is that i have complained and no one attends to my complaint and even the sales man Mr Taswald Franz does not communicate. We buy cars has the worst after sales service on earth and i will be lucky if they deliver the vehicle in this lifetime.
