    @O2 Poor customer experience in-store today. Disappointed to say the least.

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 On the Odeon website it asks to validate the special code but it doesn't work with any of the three options (meerkat mondays / voucher / card). The issue is with @ODEONCinemas booking system.

    @planetf1 @O2 You could turn off Private Address in your WiFi network settings then it will sue the same MAC address for all O2 WiFi networks and you won’t need to login.

  • CoastCyclist South Coast Cyclist (@CoastCyclist) reported

    And @o2, your 4G+ signal at Bath Spa is *REALLY* slow, even with a full signal.

  • KennySmithPhoto Kenny Smith (@KennySmithPhoto) reported

    @O2 Connection too slow to open that but if it’s switch off your phone, reset etc etc I’ve tried all that any chance it’s just a shite signal?

  • manonplatform TMOTP #RememberingStonehaven (@manonplatform) reported

    @O2 are you still having some issues in the Enfield Chase area? Can’t seem to get 4G or 5G signal, only 3G.

  • planetf1 Nigel Jones (@planetf1) reported

    Slow cap at active portals (@o2) and #iOS. Select wifi. After (too often) an eternity login page pops up. Either is dismissed as by now using lte, or asks for 2FA number, which of course arrives as text, and switching to read dismisses the login page. Yeah well thought out that 1

  • michaeljw_97 Michael Williamson (@michaeljw_97) reported

    @O2 hi. I placed an order online with £90 upfront which has come out but it says the order is unsuccessful. Does that mean the order will be cancelled and the £90 will be returned? It needed to cancel the order anyway. Any help will be appreciated. Thank-you.

  • LizHarding Liz Harding (@LizHarding) reported

    This has been going on for about six weeks and yet I am still paying for this nonexistent @o2 @VMO2News service

  • LizHarding Liz Harding (@LizHarding) reported

    @O2 I have been through all that. It is a mast issue but it has taken over six weeks and no end in sight.

  • daveelwood Dave Elwood (@daveelwood) reported

    @O2 in middle of swapping old number to new sim. On hold to customer service and it cut off. Now have no working phone on any sim
