    @snippetsofem @virginmedia @O2 Okay I would sugguest is login to the router and change the channel of the 2.4ghz and 5ghz. There is app called WiFi analyser. It will scan networks (access points) around you. Other routers on the same channel the app will show you your best channel to be on. Trust me it works

  • pickled_tinker Ian Grody (@pickled_tinker) reported

    @Ofcom @O2 Done. I will also be involving their ADR over the customer services (or rather, lack thereof). Thanks.

  • LeeCoops31 lee cooper (@LeeCoops31) reported

    @virginmedia @O2 Price hikes , customer service will go down hill

  • lexburnett86 Lex Burnett (@lexburnett86) reported

    So when can I get a discount for being a @o2 mobile customer and a @virginmedia broadband customer , your services is great but neither of you are cheap?

  • HyggeJem Jo Kneale (@HyggeJem) reported

    @vmbusiness @O2 Could you update your Twitter with a notice telling people what the issue is and whether there's a temporary solution? How long could this take? How bad could this get before you make it better?

  • 1spud12 Rob Lee (@1spud12) reported

    @virginmedia @O2 **** sake i joined virgin mobile because o2 was **** now its going back to tge o2 coverage well... bye

  • Mirrorscream Mark (@Mirrorscream) reported

    @O2 now you have announced you are with virgin, ig atleast explains my signal issues for the last 6 months.good to get an eeason to why i only have 2 bars at best and the 4g is a thing of myth. Wouldn't it be better to bring everything up to high standard, not settle for 2nd rate

  • Olithewally Oli G (@Olithewally) reported

    @O2 I am absolutely shocked by your customer service today! I have been with you for over 10 years and 3 different service agents have either hung on me or transferred me to a different department that has nothing to do with my query. Your customer care was always top notch!?!

  • oflahertyevents O'Flaherty Events 💙 (@oflahertyevents) reported

    Dear @o2 sadly with your merger with @virginmedia you can expect customer complaints to go up as Virgin don't care!

  • domvictoria Dominique Fossett (@domvictoria) reported

    @O2 @virginmedia Please don’t change, your customer service is brilliant, Virgin Media on the other hand (ahem)
