    @O2 How can you access the network checker if the network is down? I know you've had your ceiling ripped off but presumably your masts are all standing. Terrible reception today, is this due to overdemand, just no way of telling.

    Hi @O2 I logged a call in April 2021 reporting no signal in CM144HN. Since then I have been getting regular auto texts advising you are working on it. Can you please give a real update as the problem remains.

    @O2 hi there! I’m trying to talk to someone in the billing department but struggling to get in touch as the number I call gets diverted, even when I call from another number. Any help appreciated.

  • thisiswiss Angela Tobin (@thisiswiss) reported

    @O2 Hello! My mother has a contract with you but she would like to cancel it. She has dementia and has struggled to use the phone for a long time. Is she able to give 30 days notice to cancel by email?

  • rubyannelines RUBES 😁🌈 (@rubyannelines) reported

    @O2 I’ve purchased a new phone from you and had an extra of free Apple Music. The link you’ve sent me won’t work. 😩 #Help

    @O2 Its been 5 weeks. Whether engineers are aware of it or not it isnt being fixed. I get the pointless updates. Wifi calling is no good outside. Cannot get internet via 4g outside. You are breaking my contract, so probably time to cancel and leave for free.
