Unbelieveably bad service billed 50K without explanation!

<p>I have a Business account with 5 lines, on the 14 December 2016 a soft block was placed on all the lines. I phoned to enquire what had happened and I was informed that one of the lines ********** 919 used by my employee had overused data by just over R50 000 ! which inturn had exceeded the business credit limit and the lines were blocked automatically. I said that this seemed unlikely as the line is a red VIP which includes a bundle of 5gigs and it was only the 14th of the month, plus this was causing massive negative impact on the business. They agreed and said they would unblock the lines and requested a report on the data ref A7-EGDO-BN1CV. The phones were unblocked, but that evening were blocked again. After endless phone calls and unblocking and blocking, I realised the only way I was going to resolve this was to pay the R50 000 which I did on the 15th of December causing a cash flow nightmare for me. After 3 weeks of hearing nothing, I phone back today for feedback on my initial excessive data query, only to be told that the request was closed because there was no Email Address!! (I have been a Vodacom client for more that 8 years and they don't have my email adress?) So I have now had to request another investigation into the excessive data usage S4-N997A-AS3K!! I need an explanation into the data usage immediately, R50k is more than 5 times my entire account for 5 lines! I had to pay R50k just before December to unblock!!</p> <p> </p>
