On the 5/11/2009 I revceived a sms from Vodacom that 81% of my 2Gig datacard has already been used.I logged a call, asking them or how this could happen, Idon't use the internet that much.6/11/2009 I received a message that they have tried to contact me(once)but nobody answered - they assigned an agent to my query and will come back to me in 14 days.12/11/2009 I received a message, my contract is depleted.I bought a pre-paid bundle and inserted this at 13:36 and used it.On the 30/11/2009 I received a message from Vodacom that there was a massive data usage on my contract account and that my account is R5, 772.78.There is two contracts and 1 account.1 is a cell contract and 1 is a datacontract.I logged again calls complaining about the datausage, that I know I didn't used.Since then I logged 7 calls, datasupport close everyone and with no good enough explanation.I paid the cell and the 2 Gig amount and said that I won't pay the R5, 772.78 because the calls isn't resolved.Yesterday they blogged the cell and datacard.We have a high risk business to run and can't afford to be without the cell.It took met three hours on my mtn contract and 6 people at several departments to unlock the cellphone and datacard, pay the outstanding amount of the query and Candice at Vodacom refuse to refer me to another agent or a higher authority.I am feddup, because I as consumer have no rights to protect me.On Hellopeter.com I find ten other people with exactly the same queries.Vodacom just force you to pay up, because the blogged the simcards.1 Query is more than R15, 000.00, others R10, 000.00.I have the links to these calls.Today I visited again Vodacom Customer Care in Bloem, and they just said, I've used the data.2 of their technicians already investigated my pc, there is no spyware, no hacker, no mallware, no programs that have been the reason for this usage.What protects me against fraudullent billing from my service provider??The data support centre say, they did do the investigations, and I was billed correctly. If that is true, where is the data.More than 8 Gig was used, I normally don't go over the 2 Gig.There is no program, no movies, no music, none other than work on my pc. Nothing that is been downloaded in the month of November.From my 2nd call as to date, everything turns back to normal and my data usage is very low.Why all of a sudden??
