O2 Engineers
Since early January I've had b*gger all phone signal at home and all I see from O2 is a "Looks like a nearby phone mast isn’t working as it should, sorry. Our engineers are likely to be on the case already, and your service might come and go until we fix it." message.
I assume that O2 engineers wear a tutu, have little wings and a twinkly wand - or is that the fairies at the bottom of my garden?
