Poor workmanship!!

I am so disappointed in the workmanship of the Princess branch. I had a hinge repaired in the beginning of January, which I had no complains about. I then had another hinge on the same laptop repaired now. Firstly it took them a whole week for the repair with no updates (I had to consistently phone to ask when it will be ready), then the technician told me on Friday the 9th of Feb, I can fetch my laptop on Saturday at 12. Guess what? My laptop was still in pieces when I arrived and the so-called technician nowhere to be found. After expressing my frustration, they then said it will be done on Monday the 12th. I am now sitting with a laptop screen that does not close properly anymore (lob sided) as the one hinge is now thicker than the other. The glue is messed all over the bottom of the left corner, you can actually see the glue marks and this of course is white in color, which is as visible as the sun on the ocean. This is a laptop I have had for +- 5 years, and I look after that laptop like gold, is now turned into a laptop that looks like I bought it from the trash. There is no help or any resolution. Why should I be happy with such poor workmanship??
