Very bad service

I bought a Ford Ranger from MBA Auto on 17 June 2015. We had to purchase a new battery, as the old one left us standing only a few days after the purchase. I am still trying to get the payment of R 1200.00 for the new battery, as well as the service booklet from Martin. We had to take the Ranger back more than once to replace bearings, ball joints and the starter as well, as it was in very bad condition. Also, his office assistant, Hanlie, said she would send me electronic copies of all paperwork and contracts of this transaction, I am still wainting for this as well. They ignore my e-mails and sms's. When I do get hold of them, they always say, before the end of the day everything will be sorted out. This has been going on for about 7 weeks. I will never refer anyone to MBA Auto, as it is the worst service I have ever experienced. I will now be taking this matter further.
