alienware 17 touchpad peeling off

this is actually the second time this happens.
last year I got a brand new alienware 17. for 6 months everything was fine, then the touchpad started peeling off. first there was a small hole in the coating, then it grew with use. it became impossible to use the touchpad as it was unpleasant to the touch nad snagged the skin in a way that made smooth gliding imposible. I called support and they had it replaced.

a month after that I started having various problems and support replaced the motherboard. since I bought it in the US but live in israel, I had to use the local Dell suppport which uses refurbished parts, and they ended up replacing 5 motherboards, each coming with its own problems, and other parts like the keyboard, (the latter for no good reason since the problem started and ended with the motherboard provided by them, as well as any other problem since the first motherboard replacement.) and the top casing as well, since one of thier techs put the screws not in the right order and places and ended up destroying the handrest I had. my warranty ended during that time (that ordeal lasted for MONTHS.)  and seeing as they didnt provide efficient support and wanted a LOT of money for warranty extention, I didnt extend it. but now I am faced with the same problem again, which it the touchpad peeling off and exposing a non pleasant to the touch surface beneath it.

is there any way to patch or repalce it without involving the (rather incompatent, I'm sorry, but it is true) local support, or is there any way to order and buy the part without involving them? (I've had Dell support tech come to my house that didnt know the first thing about the computer and ended up bolting things wrong and damaging the computer. if I now have to pay for the fix, at least I'm going to find a private tech that knows how to deal with alienware. I've had enough heartache with this comp.)
thank you
