Callback action of seat and back cover !

Have since December a white up! with leather covers ! In June I got a letter from VW that the seat and back covers of the front seats must be replaced , as the white Keder can be replaced ! So I called VW to whether I can leave the seats inside until the problem may arise ? The answer is then I would have no more claim , if I would not make it the same ! Said , done to a VW dealer to covers ordered in July to get an appointment 2nd date when picking up the same in green ! So the 20.08.2012-24.08.2012 have been back at VW , after some excuses and new leather charge picked up again as “ready” looks it already better but the tile still looks out ! Do I have a claim to new seats from the series , since these are actually machined ?
