I don't understand the statement in bold. Are you having uneven wear on the pads? i.e. one pad wearing out more than other? If so, it could be one of the piston is stuck, causing all the pressure to be transferred to the other one which in turn in causing one pad to wear out more than other. IIRC we discussed this earlier. The pistons need to be removed cleaned (including the bore in caliper) and put back preferably with new seals and brake fluid. They might also be having a caliper rebuild kit with new pistons/seals.
If you have pics and svc is not helping, shoot an email to ktm and demand an explanation or confirmation that uneven wear is 'normal' (it definitely is not)
