    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • 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.

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

    @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

  • 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 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

    @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

  • heslrh ヘザー (@heslrh) reported

    @O2 I purchased a click and collect but there's been an issue with the order so i'd like a refund as I went into the o2 store just now to purchase it and they had it available

  • princess_knicks princess knickers (@princess_knicks) reported

    @O2 I’m now in the third day of no service. PLEASE can you put me in touch with someone who can help and update me on the fix.

  • Jakeyyd15 Jake 🌸 (@Jakeyyd15) reported

    Shoutout to @askesure - couldn’t come close to a competitors quote for renewal. But, rather refreshingly, their cancellation process was swiftly dealt with by the advisor over the phone. Unlike @O2 and @virginmedia who make it as painful as possible and hang up on you repeatedly

  • ArminderDahul Arminder Dahul (@ArminderDahul) reported

    After getting so sick of only getting a 3G signal with @O2 I left early and re-joined @VOXI_UK. I am getting 4G/5G with speeds of around 200Mbps. I should never have left.

  • kendersrule Kendersrule (@kendersrule) reported

    @O2 hi I ordered a sim for a new phone earlier today, and I haven't had any kind of signal since then. Neither new phone nor new sim are here! How am I supposed to fix this? Yes I've tried switching my phone off&on, and tried taking sim out + putting it back.

  • jemweb Jeremy Webb (@jemweb) reported

    @O2 In Christchurch and three of us on o2 cant get signal or priority to load for the offers.

  • Smith_Zachary Zachary Smith (@Smith_Zachary) reported

    @O2 4 weeks on and still reply from the fraud team. Numerous calls to ‘customer services’ and their advice is to try an O2 shop?! Please can someone from the fraud team contact me?!

  • gerrytho Gerry (@gerrytho) reported

    @O2 still waiting on a manager call back weeks later??? What’s going on ?? #fail #sameoldcrapdaily

  • SoundEngUK An Audio Engineer (@SoundEngUK) reported

    @O2 That link doesn't actually help, there doesn't seem to be anything which helps me register for wifi!

  • alexcash909 alex rakhshani (@alexcash909) reported

    @EnglandRugby @O2 A 9,10 and 5 wingers, think we could be in for some trouble here.
