billing issues

<p>i put a limit of 50 rand on my account. this was not carried out and the bill came to 10000!!!! well i paid up and put a limit again but yet again it came down to this. when i asked vodacom the shop says they cant assist i must call customer care when i contact them they cant pick my profile up. then a person by the name of Nompuouko calls froma private number to ask to confirm my id when i asked what the call is for he cuts the call and cancels my sim card. i mean this is South Africa how can he call from a private number and ask me that with out stating his reason. now vodacom wants me to pay 3600 and reconnection fees. i get that i made the calls but why wasnt the limit put into place and an sms sent to me when i exceeded it. no one is willing to assist me and the call centres cant pick up my profile so how it is im paying this account.</p>
