  • 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 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

    @lindapriestley1 @Danfudge @O2 I’ve found it to be a bit painful, takes a while to get what you need. Has the same with every network I’ve been with though other than Vodafone who charge a ridiculous premium for it

  • DLConio92 Dave-Lee Conio (@DLConio92) reported

    @O2, Hi there, I've just applied the 02 priorities code to use at an Odeon, but I never finished the transaction. I went to reuse it at a different time but it is not saying the code is no longer valid. Any help please? Thanks!

  • rharris_22 Rob Harris (@rharris_22) reported

    @Danfudge @O2 Voxi/Vodafone. Cheap, great service, additional benefits and social media doesn't use any of your data

  • Athinaengland Athina England (@Athinaengland) reported

    @O2 Hi, I was trying using the Disney+ discount but I am an O2 business customer. Is this offer not valid for me? I have numbers both on SIM only and contract business with yourselves.

  • NoOneCa33700598 NoOneCares (@NoOneCa33700598) reported

    @O2 I do not appreciate text messages accusing me of not paying my bill when I have. This is not nice and causes me to have an anxiety attack. My contract with O2 is nearly over so I will be looking for a different provider who doesn't harass me. I've been a customer for 12 years

  • zoesdevil Carl Jones (@zoesdevil) reported

    One if the worst companies i have had to deal with regarding my phone contract, misinformed & now rejecting me taking another one out after returning my last phone as it was faulty. @O2 shocking customer service.

  • Chris_Basd Christos Basdekis (@Chris_Basd) reported

    @O2 Could you please tell me how to get the PAC code? Do not ask me to call or send sms as I have no coverage for 2 days now and if lucky I will get it by 21/07. I have joined 5 days ago and your faulty network has caused already problems. Please somehow send me the PAC code.
