leatherman sa bad backup service

I purchased my leatherman wave 5yrs ago.I bought it with the 25yr warranty peace of mind.I took it over the weekend to cape union mart to have it serviced as it the mechanism were practically jamming or seizing up. i was told to pay a r250 courier fee and that leatherman would assess service /repair and send me an account accordingly. This is a terrible service,how do you promise a warranty during purchase then change your policy thereafter.
