Constant Mechanical issues and service!

I Have Had my Suzuki for less than 3 years now and have had constant issues from the beginning. Within the first few weeks of owning the car from new the gearbox had issues and had to be sent in for weeks. From the beginning I requested that the car should be replaced and was flat out denied! This problem has surfaced again and again and has become a huge headache in my life. The fact that Suzuki SA is almost impossible to reach is also extremely upsetting, one can call and call and have the line dropped over and over or once you get through there are no staff available to take your call. I was informed that the reason for this is they are all getting ready for a new launch......SO the rest of your CURRENT Clients Suffer? Well you have defiantly lost the loyalty of this client. I have been stuck without my car or at least a loan car for nearly a week and had to hound the Boksburg dealership for news on progress of my car. At this stage it requires 5 to 10 calls to either Suzuki SA or the dealership just to get one call back! For all the Hype on how reliable Suzuki cars are supposed to be, I feel this is highly overstated, not to mention the customer after service has been the worst I have experienced. The lack of service on a previous failure of the gearbox from the Centurion Branch (Where the car was purchased) was so bad and the lack of response from head office non-existent that I was even forced to going directly to Head office and demand service. At this point I demand that my complaints be heard and resolved!
