If you're confident that its not driving habits that lead to the premature failure, then it suggests an installation, quality of the parts, or oil leakage issue - got to hope that the service shop is honest and will give you the real cause once they disassemble and inspect.
BTW, driving it when the clutch is slipping can result in much more damage, such as the flywheel heat stress cracks for which the only option is replacement.
