Hayley (@Hayeley) reported from Cwmbran Central, Wales@O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

andrew hill (@andrewhillandCo) reported from Abercynon, Wales@O2 @JohnnyMercerUK bit late that isn’t it - I think he has just a few followers who may have seen this and your ‘standard good customer response’

-
Sarah (@sarlpar) reported from Henllys, Wales@O2 your coverage in the Cwmbran area NP44 is shocking, no end of people on O2 post about the poor signal especially around the Llanyrafon and Henllys/TyCanol area. When we ask about if there are any signal issues we’re told there’s not, Vodafone, EE and 3 work prefect. 😖
-
Garry Dauncey (@daunce4thstreet) reported from Pontypridd, WalesNever use @O2 recycle! sent them a phone that was in perfect condition & now they say the phone is damaged and are offering peanuts for it. If it’s damaged blame the flimsy packaging you send.
-
👑Immy👑 (@ImogensMind) reported from Blackwood, Wales@O2 my friends phone network has completely gone down all day, they can’t call anyone including yourselves. Please suggest what they should do?
-
Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, WalesTotally disappointed with @O2 customer service. A number transfer from a consumer account to business took 8 days when I was told it would take 24 hours. 3 phone calls to customer service and still not 100% sorted. #totallycrapexperience
-
Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales@jolilford @O2 Your kidding me!!! I have contacted customer services 3 or 4 times. Shocking service
-
Sarah (@sarlpar) reported from Henllys, Wales@O2 It’s been going on for months, I have friends dotted around NP44 and they all struggle making phone calls as they keep dropping out, it’s not something new it’s an ongoing issue. I’d change if I wasn’t tied in and I think you’ll find other would too if they could. So frustrating

Darth Wader (@LordoftheSplash) reported@TakeThatClouds @O2 Just moved to Smarty becuase of **** like this, at one point a few years ago my number suddenly stopped working, they’d issued a pac code for my number and given it away, couldn’t get it back, so gave me a year for nothing, as soon as that was up I was off, 02 are utter ****.

-
Dave Ogden (@daveo1880) reported@O2 are there any plans to roll out 5g in Rhyl/Prestatyn. Every other mobile provider has 5g in the area but you haven’t? 4g drops signal too often and I’m left with little or no signal to make any calls. Considering I’m paying over £100 per month it’s poor coverage
-
Andy Sherratt (@andyps1275) reported@Osprey0 @O2 Used to be that Virgin were the go-to for being the customer champion, since they merged with O2 that isn't the case. Puts me off moving home internet to them.

Cody (@CodyButton77) reported@O2 STILL charging me for a phone contract that I finished payments for in December 2025.

💎🇳 🇪 🇲 🇪 🇸 🇮 🇸💎 (@i_Nemesis99) reported@Fortnite @FortniteStatus @O2 the O2 fortnite drop what exactly did O2 customers get because if it just that generic code it is awful especially since already being shared around tbh you could have just shared the code on social media yourself instead of making customers wait
