Poor workmanship at Jaguar land rover in Umhlanga durban and JLr Pietermaritzburg.

Took my car to JLR umhlanga for a break pad /disc change. Drove 3 hrs to get to the dealership, which they were aware of. Was only told at 4.30 pm that the car cant be completed. Had to sleep in an hotel overnight. The worst happen the following day when they mention they will be doing airbag change as a campaign. Only for them to mess up the central locking system. They didnt even realise. Car was completed around 5pm the second day and they hurriedly gave the key. Car wasnt locking, on driving out. Email and wats app messages were sent with no reply. Calls made no call back until 4pm the 3rd day. The response was, it wasnt our fault, and there's no guarantee to our service. I was asked to take it to another dealership for check up and repaired. On getting to another JLR(Pietermaritzburg), they claimed it wasnt related to air bag and disc pad change. They charge me another fee and it took another 1 week for them to diagnose the fault. After the 4 day with little communication, i, called only for apology to be rendered and promise to fix the car within 2 hrs.. THEY did fix it as promised within 2 hrs only to cause another fault. Now its the front passenger window that cant be open. We picked this up and told them same time, 1 technician fiddle with it but unsuccessful. As it was Saturday, they ask us to take it away and bring it back on Monday. On Monday morning without any courtesy call, got a defensive email asking me to pay R8000 to fix the window as it wasn't related to what they did. 2nd incident within 2 weeks from JLR. Firstly i paid for central locking system that was messed up by JLr umhlanga, and fix by pmb,. Now pmb jlr is asking me to pay R8000 for another mess up. The quality of workman ship has deteriorated in the last 2 years and efficiency has been thrown out from this dealership. No accountability and the clientele service is pathetic. Speaking to the service manager hasnt helped and they keep covering up their fault.
