To purchase a phone with a guarantee that I will have service at my home location, all good to start with but then no signal unable to make or receive calls, originally was told no problems in area, finally after multiple enquiries from me I was told that there was a mast down and the engineers are working on it, for over 2 months now. I have missed important calls from hospital and other urgent messages calls dropping out. Then I finally got to talk a manager Julian a who explained all to me, she said that O2 do not guarantee coverage and that my calls were affected by my house as it was made of brick.... wow that's so efficient of her, specially as my problems were so erratic perhaps my house bricks change with weather, temperature, or for some other reason, fed up with being lied to misled and treated like an idiot, good old O2 least you made me laugh.
