Bad Client Service!

Bad service! I took my damaged Samsung phone in that's still under warranty, they send it away to the repairs centre (separate entity). Then my warranty was voided due to a small crack on the one camera lens, unknown to me, so the quote was R8000 to repair. The Samsung Ballito Store responsibility was to inform me that with this repair they need to reset and wipe all memory, but I can do a backup for R950. NO! They didn't tell me, I pay the R8000 3 weeks later my phone is back, and guess what, ALL MEMORIES, PHOTOS, WORK DOCS, ALL WIPED. Sorry Sorry Sorry is all they say. When the manager got involved when I threatened to report them, no we will come down to R650, but I have to take the phone to Umhlanga on my dime and 3 days later collect it again, no I have to setup and backup all over to backup phone and then 3 days later going through this nightmare again. Stuff that.
