Ubreakifix review: iPad 5th Gen charge port repair

Dropped off an iPad 5th gen that worked perfectly, but needed a replacement charge port (was charging intermittently). Was told 1 week, due to the part having to be ordered. It took 2.5 weeks. I sent my daughter to pick it up. She paid and received the iPad, only to find that there was now a huge bubble under the screen. She asked for them to fix that and was told to return in 30 minutes. She came back and found that there were now what appeared to be scratches under the screen. She called me and I had her request a refund while they fixed it, and that we would return the next day to pay for it and pick it up. We came back the following day. They had "reverted" the repair (by presumably de-soldering the entire charge port connector), and had somehow either disconnected the battery or discharged it completely (and added "bonus" fingerprints under the screen). They said that they thought that she didn't want to pay, so they couldn't leave it repaired?! There is no way to tell if the screen even works now. I explained the miscommunication and asked them to complete the original repair and I would pick it up later that week. They said that the manager would not allow them to do any work on the unit. Very frustrating and very unprofessional. All we ever wanted was for the unit to be repaired, and in the same shape that we brought it in. We never asked for them to revert anything.
