    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • 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?

  • 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!

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • 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.

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

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

    @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

  • Dragon2611 Matthew (@Dragon2611) reported

    @O2 Got results between 58 - 138Mbit, so seems reasonable for an early deployment. Obviously what I can't see I'd how busy the mast/network was at the time. Just glad to finally see 5G working on my Nord tbh.

  • GlassMadeArt Glass Made Art (@GlassMadeArt) reported

    @O2 We have not cancelled the order as we believe we would have to wait even longer! We have waited for a phone call back from Customer Service Manager and still not heard anything! 😔

    @O2 can someone contact me about getting a good deal on upping my daughter's data. She's trying to access her online classes and our WiFi is terrible. She currently has sim only and 4gb pm but is going to be relying on it for live GCSE lessons. Thank you.

    @O2 are offering an extra 40GB pm until July for both contract and PAYG customers. No redemption limit stated. Pretty decent from UK's largest network.

    @O2 Are you going to discount our bills then as we are paying for a service that you cannot guarantee?
