FNB Connect: Cannot Receive Calls

I migrated to a new contract on 25.06.2021

Since then, I cannot receive calls. I can make calls, but I cannot receive calls.

I have been told to try and have done the following: 1. Remove call barring: #330*1234# 2. Remove and insert SIM. 3. Turn flight mode on and off. 4. Remove any active diverts: ##004# and ##002# 5. Another magical MMI code: *35*1234*16# <- this seems to enable call barring on incoming calls, so I followed this with point 1.

It is not the device, the device is brand new, and works with other SIM cards. The problem coincides with the migration to the new contract.

I have lost a week of phone calls and business because of this.

From previews reviews i can see this is an general problem but also can see it gets resolved. Can you please get me someone that ACTUALLY know how to resolve this problem and not someone that follow the most general problem solving - as per above general way is not the way to fix it because i still have the same issue
