All calls bared

I have a huge issue with Vodacom,

*) Trying paying bill at Brits Mall shop they always offline , the result is that my account is in arrears *) Trying to get banking details failed *) Already submitted my new banking details but it seems that they did not changed it ?? Since no debit order runs?

I am fine with outcalling calls getting bar , but i am completly unhappy that my incoming calls is also now affected? Now i can call nobody to get this sorted and i can recieve no calls to get this sorted. i am on the road 80% during the day. what to do now? can somebody atleast get my incoming calls working again? I was not even called to inform me of this action.
