Suzuki - money ******ion

My suzuki jimney comes back with problems everytime it goes in for a service, i was stranded 2 times woman alone next to the road after a service, almost 2 weeks after the last service my water pipe burst, vehicle did not over heat no indication something is wrong, send a foto to the manager at vredenburg branch, vehicle gets towed in, repair the pipe, just to be told coilpacks needs to be replaced over 8000 just before christmas? I have queried that on email and they insisted on replacing both, a few days later i receive a phone call, to be told they THINK i blew a top gasket?? Really you think? We then told them NO more, everytime the vehicle is there, its the same thing, proof of this was send to Suzuki HQ they in return choose to overlook and not even take notice of whats happening or the fact that the branch is busy with ******ion. Bottom line another reputable company did a diagnostic on my vehicle, they gave me a written letter that nothing is wrong with my vehicle. What did Suzuki auto rep**** to this? They said I can take my old coil packs to be assessed to see that nothing was wrong? How many of you get your old parts back that was replaced? So bottom line? Suzuki just wipes money ******ion under the carpet and tries to get away with it on a legality well known that most branches doesnt give you the old parts back? So what do we do? Is that how they silence a customer? What happened to the consumer act?
