  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • JemmaLDS Jemma (@JemmaLDS) reported

    @O2 The problem isn’t that you didn’t answer ~ you did after 20 mins! The answer is you hung up on me with no call back.

  • jordenledger Jorden (@jordenledger) reported

    @O2 you really need to get stuff sorted sooner than expected , I’ve got told yesterday I will receive a phone call today, which I didn’t know and now I’ve been told I need to wait 3 to 5 working days to get my signal back on which is ridiculous , and I’ve been with you 4 years

  • Crabby_Patty_ Milly Billigan (@Crabby_Patty_) reported

    @O2 None of your support pages are fixing me the answers I need, and there are no network issues. I would like to be able to speak with an actual person about why I’m suddenly not able to send texts.

  • ladysmanca Simona_la tradulettrice (@ladysmanca) reported from Edinburgh, Scotland

    @O2 Thanks! As I need my phone for work I need to sort the issue soon.

  • izz_wizz not so easy davidson 🇺🇦🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 (@izz_wizz) reported

    . Anyone ever tried to get their phone services resumed by 02? @O2 I have spoken to 5 people; 2 did not reconnect my services & 3 did not call back when they said they would. O2 chat said it was fixed and it wasn’t. Still no service after 3 days. Should I change provider?

  • DJWMarathonMan David J Wright (@DJWMarathonMan) reported

    DPD UK are so rude unprofessional and never on time but thanks to @O2 they will feed back the poor service I had from DPD UK I just hope they don’t use DPD UK again
