FNB Connect Not Helpful

FNB Connect not very helpful. On my online banking profile only one simcard is linked to my profile. I have loaded airtime, data and a voicebundle to this simcard on my profile thinking it was my regular number that I use. I have 2 other simcards that I have never used, somehow one of these simcards got linked to my online banking profile. I have tried to explain to them that all the simcards are registered in my name and if they could transfer the airtime, data and voicebundle to my simcard that I use. They flatly refuse and say it is not possible. Very inflexible to a loyal FNB customer for years. I will look out for other service providers rather. I now have to forfeit the money for the reloads that I have paid. It is my bona fide mistake but I am not trying to de***** anyone.
