    @O2 I requested my PAC code yesterday via messanger. Went through all the security questions but it still hasn't arrived. Can you help please?

    @rhianna_joseph @AlexanderChrisS @O2 Girl, if only it was that simple. I've tried. I really have. Maybe if O2 could jump in and explain why I've spent over 9 hours over the last month on trying to call, unsuccessfully I might add. Still waiting on a reply to a complaint dated 03/03/23 so I'm not holding out hope.

    @PeterLa87509130 @O2 We had issues too, finally worked on 3rd attempt (PayPal and Amex both came back with error messages when both working fine on other purchases. Tried a Visa card which worked )

  • Supercyclist101 Matthew Haynes (@Supercyclist101) reported

    @O2 my contract expires later this year, and so far I won't be renewing. I bought a 5G phone for faster data speeds, but 5G in Manchester is just a joke. Check your website and just always shows a known mast issue. This mast repair must be the longest repair job in history!

    @O2 I’m really upset that it’s so hard to complete an transfer of ownership with O2. Customer Services staff told me that the user has to purchase their own account first to transfer the number to them I’m now leaving because of all the stress.💔💔 #badcustomerservice

    @O2 absolutely disgraceful service from you today. A newly bereaved widow asked us to sort out her late husband phone. We had to hang on for 27 minutes until someone from the so-called bereavement specialist team could be bothered to answer the call and then be downright rude

  • sophie_dickings Sophie Dickings (@sophie_dickings) reported

    @O2 It's impossible to get through to you. Aura is no help and I'm going round in circles!!
