    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 don't follow through on their rewards when people sign up for new deals etc! Be aware that they make it ridiculously difficult to go through any customer care routes and don't respond to emails or call back when they say they will #AwfulCustomerService

  • djt81 Dave (@djt81) reported

    @O2 paying top whack for a 5g contract and to be honest the service is average at best. Are you having ongoing problems in the West Yorkshire area

  • DeepingDo Ashley Baxter (@DeepingDo) reported

    I'm in an @O2 call queue listening to the absolute worst call-queue music I've ever heard in my life.
