Vodacom Overbilling

Hi,<br> Vodacom has locked my account I do not receive data and cannot use my sim card but pay R59.00 per month.<br> With regards to my account, a consultant called me few weeks back and asked me to call enquiry to sort my account. He blames me for allowing the amount to go high twice and he said that if they ds credit me it might be half of the amount he was not sure that it will be that. I received no credit as yet.<br>
