XPS 9500 touchpad

I've got the same loose touchpad that's been mentioned here by a few people, but having no luck getting it fixed. I reported it in July and after Dell sending a replacement palmrest that had damaged corner out of the box and still had the same loose touchpad, the following two palmrests they sent also had damaged corners! I was told over the phone that they would be sending a replacement laptop but now there is no mention of that and they keep requesting photos and videos of everything which I've provided 3 times! Clearly the tech support don't talk to each other, and they're certainly in no hurry to reply to me. When you pay top dollar for a laptop with quality issues like this and it takes 4 months with still no resolution, it's pretty disappointing, and it's frustrating to use and now the lid doesn't close fully because of the broken corner!
