The biggest mistake I made was to call Fnb connect now I can't make calls

<p>After speaking to fnb connect telling them that people have been complaining that they can't get hold of me the agent tells me to dial ##002# after that guess what i can't make any calls. I call them on another line and they tell me to roam on different network. I mean she doesn't even listen to what i am telling her she tells me she's troubleshooting. Am now stuck can't make any calls even to 147. After a while managed to roam on vodacom only then could I make calls to 147. But to other people it says I have depleted my credit limit on my contract. When I dial *111# to check my voice minutes it says my sim card is blocked. I call 147 again and they tell me they are offline they can't assist me. Exactly what is going on at Fnb connect ??? </p>
