    @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?

  • 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.

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • 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

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • arigork Ari Gork (@arigork) reported

    @O2 Morning team. The area surrounding my kids Nursery has no 4G and I’m lucky if I get a decent 3G signal. How can I report this? Your map shows it’s a known bad signal area so guessing a tower is needed. The other networks have 4G in the same area.

  • JD_Mac82 Jon Mac (@JD_Mac82) reported

    @O2 strike again…. Cheers for the free Apple Music for 6months, just because you can 👏👏👏 Top service and customer retention as always! #O2 #AppleMusic #GreatLoyalty

  • LauraRiv81 Laura Rivett (@LauraRiv81) reported

    @O2 can someone contact me asap about a complaint. Getting nowhere in the chat function on app and phone! Took 2 extra contracts & regretting it now. Close to cancelling them all and I’ve been with you since 2005!

  • Adventurous_Dee Adventurous Dee (@Adventurous_Dee) reported

    @O2 network for 24 hours leaving at higher risk because if anything happened within that time frame she wouldn’t have been able to contact anyone 6 hours away from family and her support system I have watched call to several different customer service agents just to be messed

  • tomcrouch32 Tom Crouch (@tomcrouch32) reported

    @O2 I am currently in Rome Italy and have no way of accessing my data to use my phone. I’m having to use Wi-Fi only. I have gone through every conceivable action advised by your online help via the o2 app and still nothing. This is beyond frustrating. Help.

  • Faiza44312415 Faiza (@Faiza44312415) reported

    @O2 2 bills received this month instead of 1!? Not clear why this is. Can't get through to anyone to get this sorted. Please can you support.

  • Becs1D Rebecca (@Becs1D) reported

    @O2 hi, I’m wondering if you could help me with a question I have about my phone bill. I can send more info in DMs.

  • NeilIMcKechnie Neil (@NeilIMcKechnie) reported

    @O2 can someone please help me with my voicemail. I’ve tried your contact centre 3 times and they keep telling me they’ve fixed the problem and they haven’t!!

  • IrishMa88348067 Irish Man ⭕🇺🇦🇵🇸 (@IrishMa88348067) reported

    @MickKennedy76 @O2 aren't much better. I took out a new phone in Oct 21 and about 6 weeks ago it started playing up. I contacted O2, sent the phone to them only for them to confirm the fault wasn't covered by warranty. 20+ years a customer with them but it will be my last contract with them

  • Saltnpepper4eva Joseph Kelly (@Saltnpepper4eva) reported

    @O2 @tomcrouch32 Do you respond to DMs? It’s been a week since you asked me to send you a DM about no signal and you still haven’t replied.
