Charged double for services

On 1 February, without having made any calls, my phone was soft locked. I called the call centre and they said their information hadn't updated from Jan, they increased my temp limit from Jan to open the line and said that I wouldn't be charged and by 3 Feb everything will be sorted out. I had all my minutes, data and sms's so it was strange it would be soft locked as that only happens when you finish your minutes and go over your limit. On 4 Feb, my phone was soft locked again! I called the call centre again and now on the vodacom site it showed that I in fact had been charged in the month of feb for calls and data (yet I still had data and minutes and sms's - PLENTY)! The agent I spoke to this time said he would escalate the matter, they would reverse the charge and open my line as there was an error since he could also see I had all my available minutes. Then a lady from CIC called, the rudest person I ever spoke to, and she demanded I pay this Feb charge, even though its an error from Vodacom side. She never listened to what I said, rudely interRupted and as a result I still have a charge on Feb that should be reversed as I already am paying on contract for the service!
