worst service ever.

I bought a Nissan sentra 11 months ago. 5 days later reported a problem. Motor deal ormonde service advisor said it was normal. On the 1st service reported it again. I was told bring the car in when the problem is happening. I then reported this problem on this site in November 2014. Finally Nissan South Africa got involved and I was happy thinking my car will be sorted out. They found that the factory over filled the gearbox oil. Took them 1 month to drain the oil and put in new oil. This was only 1 problem out of 3 problem that was looked at. Then the gearbox problem persisted and the hard starting and the breaking. So the car went in again for 2 weeks and they only replaced the gearbox. Then the car went in for another 2 weeks for the breaks and the hard starting. Breaks was done and still is a problem, gearbox limits for a auto(never heard off). Nissan cannot find a fault on the hard starting but has admitted there is a problem on my car. This was 3 weeks ago. I have called emailed and left messages for the manager of the customer care to call me almost 1 month ago. Still no call back and still no solution. So you decide with service like this do you really want a Nissan.
