    @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.

  • 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?

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

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

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

    @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

  • 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

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • 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!

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • Propertygaluk Claire Mansell (@Propertygaluk) reported

    @O2 hi I’m currently abroad and trying to use my mobile data which seems to be blocked as I can’t remember my sim PIN number. Can you help?

  • ApricotHearts 🦋A🐈‍⬛ (@ApricotHearts) reported

    @O2 quite honestly the worst company. Shoddy phone signal in North Wales and argumentative staff who will bait you and then hang up.

  • emmachammond Emma Hammond (@emmachammond) reported

    @gi38928705 @O2 @TheO2 That is awful have you complained to the FSA? #O2MustDoBetter

    @O2 hi I’m trying to add on my free extra on my phone I got yesterday. However when I go to add audible it comes up there’s a problem. Can you help please?

  • HiringinEMEA Heather Brady (@HiringinEMEA) reported

    @virginmedia @TheBHF @O2 Please confirm that this is your address to cancel- Winnall Down Alresford Road Winchester Hampshire SO21 1FP

  • greendayjade Jade-Emily Till (@greendayjade) reported from Dewsbury, England

    @O2 hello! Is it possible for you to help me switch my SIM card over using a pac code? I did try to do it when I ordered the SIM, but it doesn't seem to have worked?

  • nickofmn0506 Nick Oliver 🇬🇧 (@nickofmn0506) reported

    @giffgaff and @O2 seems that this is not the best network for use on a canal away from civilization. Can anyone recommend a more reliable network that may want some promotion on my other profile and social media as I continue my lone canal journey. I don't mind advertising

  • danjvalentine Daniel Valentine 🏳️‍🌈🚑 (@danjvalentine) reported

    @O2 @ComplyandBye Is it still true if they increase it more than 10% we can cancel with no penalty because nearly 20% increase is disgusting and absolutely taking advantage and I have 5 lines with o2.

  • IAmMattRice MattRice (@IAmMattRice) reported

    Yet like clockwork @O2 will put your bill up while not being able to deliver on the service you pay for. They would honestly shake your hand while spitting in your face. Disgusting company and I can’t wait until my contract ends.

  • azhaarashraf Azhaar Ashraf (@azhaarashraf) reported from Kingston upon Thames, England

    @O2 Can you please help me as I can't send you a direct message
