WeFix has broken my iphone

On the 25th of September 2017, I took my iphone 6 to WeFix at Centurion Mall for a screen replacement, I then received the phone back later that day. The technician wanted to hand me the phone with screen separated from the phone on the one side, but then fixed it an hour later. Prior to the screen replacement I did not have any problems with my phone, it was perfectly brand new.

A day later, my phone started to reboot continuously and I couldn't figure out why. On the 5th of November 2017, I took it back to WeFix Centurion Mall and explained what happened, they said it might be the battery and went ahead with a battery replacement and a few hours later they contacted me and stated that it wasn't the battery that was the problem but that it might be the software that hadn't been updated so they went ahead with a software update. The next day when I came to collect my phone at the Wefix Centurion Mall shop, I attempted to start the initial setup and when I started with the Apple ID set up while in the shop it started with the same problem that I brought in in for. I then kindly asked the technician to please figure out what the problem is and he said he would do a screen replacement because it might be dirty inside, so they did that and later that day I was told to come collect my phone. It started rebooting again, I then took it to an Apple approved technician to do diagnostics on the phone and he stated that as he attempted to update the software it continued to display error 9 and that the technician damaged some cables in the phone when he replaced the screen. He then advised that I return the device to WeFix at Centurion Mall to do another screen replacement based on the guarantee and all the costs involved of the previous repairs and battery replacements and software updates that was done. On the 22nd of November 2017, I took the device to WeFix at Centurion Mall again and explained what the Apple approved technician told me and they said they would replace the screen for me and sort out the error 9 and the reboot problem. They kept it for a day , I had to contact them twice and ask for feedback, when I went to collect it on the 23rd November 2017 it was still having exactly the same problems.

I cannot afford to buy a new phone and my phone was working perfectly prior to the repair in September. I need to have this issue sorted as soon as possible, because it does not seem that the technicians working at the WeFix store in Centurion Mall have a clue what to do. Their excuses were from watermarks (my phone has never been in contact or near water or any fluids) to "it's normal". I need a functional phone or I will take legal action.
