    @Termehhs @O2 If you really annoyed maybe retweet using BBCWatchdog, WhichUK, Ofcom, Martin Lewis tags. I only ask as the network is total rubbish and without them doing anything it’s only getting worse!

  • rosstheconsumer Ross (@rosstheconsumer) reported

    Hi @O2, how can I cancel an order I placed - which said was in stock at time of ordering - but was actually out of stock 10 mins later. I can’t see the order on myO2 so how can I cancel it?

  • itsmrsmida Mrs Mida (@itsmrsmida) reported

    @O2 I have been trying to talk to an advisor for 3 days now over an automated service, yet 202 called from my handset results in me being hung up on! #worstservice

    @O2 There are numbers, you just seem unwilling to share. The other numbers mean being bounced around 1st line support with operators working off scripts & having to escalate. It takes literally hours of being asked daft questions.

  • HezBarr Heather Driver (@HezBarr) reported

    @O2 currently in London with a 5g capable sim and phone yet only getting 4g! My hubby with same phone can get 5g. Don't know what's happened to my phone help!

  • sheritzy Sherri (@sheritzy) reported
