FNB Connect problems, can't make calls.

I am a FNB Connect customer. I have not been able to make calls since Monday, 4 Nov. I have reported the issue numerous times. Client services has escalated my case 3 times. With 3 different reference numbers. I have waited days for feedback and for technicians to call me. I have had my sim card replaced, I have just had no joy. I spent 1. something hours at the bank today getting my sim card replaced and have a sim swap done. That was at 11:40 It is now 15:35 and I still can not make calls. I have lost an entire week's worth of productivity due to this matter. I need my cellphone service restored.

I have been very patient. Voice logs will show that. I have spoken reasonably and with respect when dealing with the connect staff. But I am now starting to lose it.

I want HELP! PLEASE! I can't afford to lose any more productivity.
