Nissan South Africa towing service provider poor service

I am very disappointed with your car towing service provider because my did not arrive on agreed time at the dealership which caused so much inconvenience. Also I bought Nissan Magnite 1.0 acenta last year in March but it's already giving me problems, the car has system breaking fault and could start. This cause so much inconvenience as I have to wait to from the dealership without any estimated time on the possibility of getting my car fixed or being updated. I am really disappointed
