I agree, the porting of a number is fraught, it should be a daily and faultless operation. In my case they messed up porting my number so bad my wife left me and went back to the Phillipines. My only recourse was to complain bitterly to customer services which I would urge you to do. I was offered 6 months free services of bothe mobile and broadband (inc tv). Poor compensation for the loss of my wife but I took it so dont let them get away with it. Maybe then they will reconstruct their operations.
