WeFix or WeDestroy

Discovery Insured, logged a claim for a screen replacement & was advised to take my phone into WeFix :( I should've checked reviews on WeFix before taking the phone in. Apart from the many issues admin issue encountered with WeFix i eventually pick my phone up on Thursday Morning (17 May) and somehow the battery is flat and won't turn / stay on. Paid my excess and left for the office, where i plugged the charger in and left it to charge. +- 2 hours later i check on the phone and its on 70%, which is odd as its usually a fast charge. about about an hour later the phone is still on 70% charge, i then remove the charger and decide to charge via laptop usb..and voila it jumps from 70% to 100% - i grow more concerned and remove the usb charging cable from the laptop and leave the phone as it. Much later in the afternoon, around 4:30 in the afternoon i decide to insert my memory card and simcard and start using the phone on my way home, and as i switch the phone on the battery is on 82%, please note the phone has been off since it showed the 100% charged status in the morning. +- 2hours later (when i'm home), a short 2-5 minute phonecall and 1 tweet later, the phone dies as i take a picture of a business card. as i type the phone is on 20% charge after being on the charger for about an hour or so.

Upon a thorough investigation of the phone, the screen isn't fully flushed into the phone frame or mechanism and the bottom right part of the screen is literally coming / peeling off!

Dropped the phone off for a screen replacement, and i'm now stuck with a shoddy job on the screen replacement and a new issue with my battery....

what must happen now?
