The Reading assistant manager of O2 lost the most important memories of the 1st month of my newborns life, just to get a sale. My husband went in as he had broken his phone and needed a new one. I met him at the shop and when talking to the assistant manager he said I could get an upgrade with a £200 cash back. I thought it sounded good but said I need to back up my phone. Whilst looking through my phone to see how to back it up properly the assistant manager put his hand out and said let me do it... I thought he wouldn't be in that position if he didn't know what he was doing... I handed him the phone and proceed to tell him I have alot of invaluable memories on there that I do not want to lose to which I was told he knows what he's doing. He said it was backed up handed me my phone and we went home to find nothing from my old phone was coming up on the new one. We went back to O2 the same day to be told I was being impatient and that I needed to leave it and let it all load up on the new phone. Extremely worried and distressed I went on to my laptop to see if my Google had been backed up with photos and videos but there was nothing. I logged on to my samsung cloud, again nothing backed up. We left it 24hrs and went back to O2. We were waiting for the same guy to have a look when another assistant took alook and saw that the phone had not been backed up properly. Finally the AM took the phone, reset and charged it, something started to happen, he was addiment that he had done it right because all the photo's from before it was last backed up by myself had started coming through. I told him these were from 2023 but again I was being told I was wrong and that I needed to let the phone do it's thing. We went home another 24hrs went by and nothing. I knew all the memories of my third trimester to the 1st month of my newborns life were gone and there was no way of getting this back. I couldn't bring myself to go back in the shop and talk to the assistant manager without getting angry or bursting into tears. I emailed O2 complaints explaining what had happened, I wasn't even looking to get anything out of it, just to make sure that this doesn't happen to ANYONE ELSE! and I've heard nothing back from them. I'm beyond heartbroken and crying all over again writing this and so so angry that they treat their customers this way! I will be going back to O2 and demanding that my contract is cancelled. I want nothing to do with them ever again.
