Good service - most of the time
I have been with O2 more years than I care to remember but the service has been very good. Love the O2 app which lets me keep a check on current usage for myself and daughters phone so no nasty surprises. The only down side is recently there seem to be more black spots wher I have no signal ..... What's going on O2 ? Other than that faultless from the people in the store to those on the help desk -always a pleasure to deal with. Exceptional customer service.
