We Buy Cars Nightmare!!

I bought a Bmw m135 from Cape Town beanch.. Clifford and Corry and actually the whole branch assisted me.. was a struggle buying the car and all the extra costs and to get it in Johannesburg. Anyway got the car here and drove to the Centurion branch to collect the car, they had chosen the incorrect type of interest rate for the deal and struggled nearly 3 hours just signing for the car... got the car and drove 30min with it and it broke down.. they collected my car with a low bed and 23 days later still dont have my car.. JVR diagnostics fixing my car yet nothing is happening, they said my car was ready on Friday 12/02, drove to Pretoria to find that the car is still broken and they sent me home.. Almost a month without a car, almost no feedback, I have to follow up with everything and I am extremely disappointed.. will never support We Buy Cars again as a first time customer and will never refer someone to you guys, just a headache and a pain each and everyday.. poor customer service and after sale help..
