No Happy with FNB

I am so frustrated with FNB.

FNB connect does not work since last week I cannot make or receive calls. Sim card status when I check on my phone says server unavailable and status unknown.

I work from home and my clients are unable to contact me and this is frustrating and putting my job on the line.

All MMI codes for cellphone banking are invalid and does not work.

I've tried the new banking app and guess what, the number linked to my profile is not even mine. How is that even possible. The OTP gets sent to an unknown number.

I logged the call for this yesterday and no one is getting back to me.

No solution is given instead I get SMS that FNB cant reach me, off course you wont be able to reach me as I am not getting calls on this sim card. Please resolve this as soon as possible or change my number back to Vodacom's network as soon as possible.
