  • lmarysiajones laura (@lmarysiajones) reported

    @O2 your customer service is appalling… been on the phone for 2 hours and won’t let me send a message via the app either. Sort it out otherwise looking to go elsewhere!!

    @O2 the McDonalds O2 Priority perk didn’t work today, had major problems last week too. Stop offering things if you can’t get them to work properly, it’s bad enough your data network is useless but broken perks and zero support from you is very frustrating…

    @O2 hi, The code wouldn’t scan in MK Centre and I clicked on it in front of the staff member. They rudely told me I couldn’t have my selects as it’s not working. Their attitude was disgusting.

    @O2 just tried to get the rewards @McDonaldsUK chicken selects. Code didn’t work on self serve, went to till, staff said not working nothing they could do didn’t even attempt manual input! Poor customer service & now can’t redeem 1/4lb cheeseburger instead! Some reward!!

  • ShakeIslam Shake Islam (@ShakeIslam) reported

    @O2 tried using the McDonald’s code for free chicken selects, and it’s not let me claim. I have the code, I am within time limits but the branch at Romford is saying they have problems with lots of people and lots of codes!

    @O2 crap customer service called 3 times over the last 2 weeks trying to get through to discuss this outrageous bill but every time your operator answers they cut me off. I need my services connecting my son has severe medical needs and this is my only form of contact out
