Sent my bootlooped LG G4 for repair but took them a month to fix it. I don't mind about the duration of the repair, what I'm mad about is after they fixed it. I sent my phone together with battery and back cover (as per LG Rep instruction) but didn't received my battery. I asked them about it but told me they didn't receive any battery. (Really?!) Good thing i have extra. I also got my case but with few broken latch and it won't lock with my phone anymore. I just used my protective case to tuck it.

Customer service is really bad! They didn't even bother to tell me that my phone is fixed and been sent for delivery. Didn't even spent a little time to write a short email hey, your phone is done, here's a tracking number blah blah blah!

Won't deal with them again!
