Automotive weelee car dealership

I bought a car at weelee in centurion on the 24 February, collected on Saturday and on Tuesday the 30th too the car back for Breaks, windscreen, roadworthy, and service and key replacement, no one from the dealer called to update me the car was returned on the 3 Feb, car key not working, windscreen not replaced, brakes replace but lining not changed, minor service done instead of major service, after length sms I took the car back o the 13 march to rectify all that, again no communications was given had to follow up, to thisay I havent receive my car and I have to pay installment to the bank month and I have been using the Bolt to work which I incure unnecessary expenditure and no one is coming to the party. I bought warranty and motor plan but when I ask for details no one is willing to give me detail the service is very bad and I was told at some stage by the sales manager he doesn't care as he has done his job the after sales manager must do his part as well
