  • johnhanc1982 John Hancock (@johnhanc1982) reported

    @O2 still no response or resolution.... Getting paperwork ready for my solicitor. Better not stop my mortgage application!

  • ChrisMc70034476 Chris Mckenna (@ChrisMc70034476) reported

    @angelazhay @EnglandRugby @O2 I don't know where the slow thing comes from, his delivery is really quick and high quality. Mitchell is a good player but I'd argue better from the bench when the game either can open or you need a hail Mary.

  • AinsleyAllister Ainsley Allister (@AinsleyAllister) reported

    @O2 The ongoing problem I am having since before December with my phone cutting out with every call is now becoming a joke and is unusable. This is not a problem with my phone as all the people living in the village is experiencing the same problem! What is being done about it?

  • Gabriel07796800 Gabriella (@Gabriel07796800) reported

    @O2 Why can i not getting any help from customer service? You would think with my contract ending you would want to try and keep me as a customer.

  • NathFerguson Nath (@NathFerguson) reported

    @VMO2News @O2 @UswitchUK Yeah the the network which never works data speed is constantly slow and useless and you rip off your customers with your prices meaning we pay more for less.

  • Mistro4ndy Andy Hunter (@Mistro4ndy) reported

    Service from @O2 and #dpduk is disgusting. For someone to open my parcel from inner part, take out my new phone, take that and the cable, put it back in then deliver it looking like any other parcel and nothing is being done.

  • B15Dan DanB15 (@B15Dan) reported

    @joycey505 @EnglandRugby @O2 You need to watch more closely then. Maybe learn the difference between managing the game at the beginning and speeding it up at the end with a tiring defence. Damage had already been done to the Welsh orchestrated by JvP. Your view is because you don’t like box kicking?

  • bigwows Bigwows is elsewhere too (🦣🏴󠁧󠁢󠁳󠁣󠁴󠁿)💚🤍💜 (@bigwows) reported

    @theroyalfactor @O2 Have never yet used one of those signal checkers that was remotely accurate. 5G is very spotty here too, but 4G is mostly ok so I’m not too fussed.

  • susan_kelly susan_cowling (@susan_kelly) reported

    Hi @O2 who can i complain to about my bill? Huge charges during my recent USA trip. But it wasn’t until 7 days into my trip you text me to inform me there would be charges. By that point the damage was done. My contract is up in two months, I’ll be seriously reviewing that now!

  • bigT__26 Tel (@bigT__26) reported

    @O2 are a sham it seems. After making promises about refunding charges for being out of the country for a long period of time they go back on their word! So much for appreciating customer loyalty. Looks like one of their CS team has fobbed me off. Time for a new provider.
