I've Never Been So Inconvenienced In My Whole Life

I booked my vehicle in for repairs on the 31st of July 2014. After I got the vehicle back it broke down after using it for 700kms. I took it back in October to change the coil pack they had installed for a new one. They informed me that it will take 2 weeks for my query to be processed. After 2 weeks the called to inform me that the query was finalized and they will install a new coil pack. They called me to collect my vehicle and it broke down again the very same hour. I had to pay for a breakdown to take it back to them. The same coil pack blew. I had to wait again for another query. After that same process they installed yet another one that also blew while driving to Durban on that very same day. They informed me I had to get my own breakdown to tow the car back to them. I got a call from them in November informing me I have to pay R8000 for a new module after paying R14000 for the previous repairs. I didn't hear from them the whole of December and January. They called me in February to let me know that my vehicle was damaged by hail and they are still repairing it. Now its April and I still don't have my vehicle with me. Its going for a full year now.
