3 times the charm?

A year ago I had my screen fixed at Wefix, formally known IFix at their Brooklyn branch in Pretoria. My screen was fixed but thereafter started experiencing a few other problems firstly the screen wasn't placed symmetrically took it back and it was "fixed" a few months down the line the ***** at the bottom of my screen was exposed and it came to a point where it fell of and the screen became wobbly. I took it back to the branch and it was "fixed" a few months later(now) I started noticing that my screen is loose and because I ,ever since the incidents put my phone in a pouch I never noticed these changes, now my screen is lose and I can literally see inside my phone. My screen is not responding, cannot do anything with it at this point and time. For the past few incidents I had been contacting the manager at the store Samantha. Honestly if this isn't delt with I would like them to return my cracked screen from last year and they can take back their screen which doesn't work. And after the two other times I had to get my screen protector replaced at my own cost which costed me over R400, thus if not corrected I would like to be reimbursed my R3,499 because this basically costs me more than enough to buy a nee device not only these costs but also my traveling costs.
