service is poor,no attention payed

I wrote a complaint in august to absa as I have given a dealer enough time t sort the problem owen met with us and the dealer promised that the car is booked for Wednesday upon noticing that the car has not moved one bit from the dealer's premises i called to find out he told me that the postponing the date and I'm not informed of such changes . I have asked to cancel the contract , Owen from absa tried to sort the problem he promised us the meeting with his manager of which it didn't happen i believe i have followed all channels to lay my complaint , no proper human being buys a car and own it for a week and continoulsy pay for something they don't have
