Utter waste of time contacting these non-English speakers who just contradict themselves. I hope O2 make charitable donations to counter the amount of stress they cause to people. We ring with a problem and end up frustrated and no further on. People don't have time for this. Appalling service for a complaint of reduced /no coverage. Disgusted. Funny enough they no longer send texts asking you to rate their customer services 🤔 I wonder why!?!
