    @apakula @O2 Wow. That's a lot. How many months of service was it supposed to cover?

  • kaxtherine1 Katherine (@kaxtherine1) reported

    @O2 how do I pay off and cancel a phone contract??? Thanks

  • lucyolivia19 Lucy (@lucyolivia19) reported

    @O2 my data hasn’t worked for months yet every time I complain, it just gets closed because I have ‘used data’. That’s only because I have it switched on trying to use it! Oh and the mast in my area has been broken since April so cannot use data there either.

    @O2 Hi, I’ve just tried to connect whilst outside a tube station and it’s done the same thing… there isn’t an option to “register”, the “Help Signing In” doesn’t provide any relevant support and I tried to call 202 but after selecting options to speak to an O2 Guru it hung up on me?

  • siana_chand Siana Chand (@siana_chand) reported

    @O2 honestly the worst. So so so unhelpful

  • steve5424 Stephen O'Donnell (@steve5424) reported from Glasgow, Scotland

    @O2 I'm still not able to make recieve calls on my new watch. I activated the esim but the watch is still showing as emergency calls only. Not connected to network.

  • lucyolivia19 Lucy (@lucyolivia19) reported

    @O2 @O2 it’ll work randomly for about 5 minutes and then stops. If I manage to get data it’s often 3G or extremely slow. I’ve been contacting you about it since April.

  • AyadGazi Ayad A Al Gazi (@AyadGazi) reported

    @O2 O2 is one of the worst network if not the worst ever!! Over 6 weeks of complaints and over 537 minutes of telephone calls and over 10 times been promised a call back … nothing received to this day!!!!

    @O2 went to pick up my Samsung galaxy watch 4 today but couldn't have it as o2 not working 😕 😪

  • ItsJamieIRL ItsJamieIRL (@ItsJamieIRL) reported

    Hi @O2 I’ve heard masts in my local area are over subscribed & currently I’m getting very poor signal for the past few days & months at times. I’m paying for something I can’t use? Also heard there’s going to be no solution for a long time. How can this be resolved?
