  • AlexandraMyers2 Alexandra Myers (@AlexandraMyers2) reported

    @O2 Rather than telling me to look at the network tips - why don’t you confirm if there are outages - as it isn’t just me who has a problem ! I would like to know if there are o2 masts down ? I tried speaking to someone - and the line went dead!!!! So now what?
