SUZUKI JIMNY - FALSE ADVERTISING????

The Suzuki Jimny has been extensively advertised for how strong and robust this little vehicle is, and how it can manage any terrain. After 2 years (full service record) and only 27 474 km on the clock the gearbox/clutch went!! I was then advised that this would not fall under the warranty, as this is regarded as wear and tear!!! i have driven manual vehicles for 35 years and NEVER had an experience like this! It is impossible to get hold of any person in a senior/management position to discuss or contest this matter. I am most disappointed and would love to be able to speak to someone who can help me. Please can someone assist????
