Original contract made by phone included call barring - mobile & premium rate- applied by BT. All ok until I increased to BB Opt 2- still paying for call barring but it was not active which I discovered when bills were significantly higher than expected! Apparently I am supposed to activate it myself with code that I had not been given! Now discover that to bar mobiles I am also barring National and inter-national numbers. In order to make a national call I have to key in a 10 digit sequence before I even start dialling the number I want. Surely BT technology can isolate mobile numbers starting 07 without blocking standard national numbers? Anyone else think this is odd?
