SHOCKING SERVICE BY FNB CONNECT.....

I am making use of the flexi package that FNB Connect is offering for the past year. All I can say that after a year of using it, I'm very disappointed at the level of service I am receiving and the fact that for the past two months I am receiving bills in excess of R1000 for 'out-of-bundle' data charges. I buy data monthly on a Pay-as-you-go basis. My flexi package allows me to choose the minutes, data or sms I want on a monthly basis, but I'm only making use of the minutes(NO DATA, NO SMS). Spoke to an agent, they apparently put a 'soft lock' on my sim to block the 'out-of-bundle' data usage. BUT IT STILL HAPPENS, it does not even show in my online backing profile.
