  1. I just wanted to report that the manager of your Richmond branch was wonderful. He spent hours with me, sorting out my phone, with kindness, respect and consideration..
    For the attention of L Schiller.

  2. I could not have received more help from the manager of your Richmond branch with my problem which took hours to fix.

  3. Subject: Account number GED42735256

    To whom it may concern (Fraud Team)

    I am writing regarding the above mentioned Account which I have been paying for since August 2014

    I am trying to get to the bottom of this account which is proving very difficult, I called o2 at 11.08 on the 5th January 2023 and spoke to one of your colleagues she established that this account does not appear to be in my name, so after a lot of toing and throwing with her manager and myself I was told that this would now be put into your hands, I was told to expect a call from you (the fraud team) within the next 3 – 5 days which never happened, which was very frustrating, due to your which I can only say inefficient call system I called again at 10.55 on Thursday the 12th January 2023 only too be told a similar thing that they had spoken to their manager who said that they had spoken with the fraud team and that I would receive a call from you within the next 24 to 48 hours, again this never happened !!! you can imagine my annoyance at this point as o2 have been taking money from my account for the last 9 years (a sum of around 2 – 2.5 thousand pounds, which I’m looking into now) and are unable to tell me why?? I called again at 12.15 on Monday 16th January 2023 which I had a getting nowhere conversation with another one of your colleagues for over half an hour, she told me that her manager would call me yet another brush off all I got at 12.51 was a text to say “I will be calling you ASAP” 02 MANAGEMENT TEAM, do you think that this acceptable ?? I don’t !! well you probably guessed it I heard nothing so I called back at 2.46 spoke to another one of your colleagues who told me to contact you direct, hence this email.

    I must say that I had a call from o2 at 20.39 yesterday which lasted 3 seconds I answered immediately so please do not say we tried to contact you!!

    All I ask is that somebody has the decency to contract me to sort this issue out

    My name is Richard Plain

  4. I’ve have a complaint about a payment that I didn’t give permission to withdraw from my account. The account concerns my mobile phone number
    The number. I would like to know why it was taken out.

  5. I have an issue with my phone where I am unable to recieve/make calls, connect to Internet, WhatsApp or recieve text messages unless I am at home on my own wifi. My phone states there is no network and I’m not registered. This has been going on for three months.
    The issue has been raised 5 times with each time being escalated to complaints review team.
    No one has dealt with the issue, no one has called me back, no one has acknowledge the problem..
    I’ve been totally let down by o2, thier customer service is appalling.
    I don’t know what else to do, maybe stop my direct debit and quit my contract.
    My phone is a Samsung flip, so not exactly cheap, all I want is a phone that works and some help.

  6. What a disgusting way to be treated by o2. 4 months story after story . Lies and just cut you off.

    I recommend usieng another network as this one being o2 is a disgrace and all they do is lie and give you a story and pass you on to someone who can’t help or they put you on hold for an hour and then cut you off.
    I will definitely be moving my 2 accounts as well as the other 7 ,I pay every month.

  7. Appalling service ,, I was the victim of fraud on 21/09/2023 !!! After dozens of phone calls ,many emails , and at least 3 letters ; O2 has not sorted the problem ,, I am sick to death of speaking to people who have a very limited grasp of the English language !!!

  8. I am writing to express my disappointment with the customer service I have received on three recent occasions. Unfortunately, on each interaction, whether online or in-person at a store, I felt unwelcome.

    This has caused me significant concern, especially considering my long-standing loyalty to both O2 (since 1991) and Virgin (since 1990) following the merger. While I initially decided to stay with the company after the merger, the recent service interactions have unfortunately pushed me to reconsider my options.

    Tonight’s call regarding my mobile contract left me feeling particularly frustrated and compelled to switch providers as soon as possible.

    I value my relationship with my mobile service provider and believe in good customer service. I urge you to investigate this matter and take steps to ensure such experiences are not repeated for myself or other customers.

    I look forward to hearing from you regarding how you plan to address this issue
