Vodacom could take more than you bargained for!

Ever entered into what you think is a fixed monthly cost contract with Vodacom? Im sure most people have as we obviously don't want to be met with a massive bill. BEWARE, YOUR CONTRACTS ARE PROBABLY NOT CAPPED!!! Vodacom is getting away with billing and debiting massive amounts by leaving data and call limits to rise sky high even though what they sell is supposed to be a fixed monthly contract. These bills can run well over R10 000!! This is exactly what happened to me, I went into a Vodacom shop in Clearwater mall and discussed two identical cell packages for my two kids. I have had expensive bills in the past so I made sure to explain to the Vodashop representative that I wanted fixed monthly cost contracts. He offered me two smart S contracts with 75minutes and 200mb data for R399-p/m. He explained that once the limits were reached the phones would be soft locked but they could be topped up by purchasing pay as you go vouchers. NOT SO! On my daughters phone it soft locks every month however on my sons phone I have data bills of R6028.11 and R11335.99 respectively! I raised the issue with Vodacom on the 30-03-15 and have e-mailed +/- a dozen times. They have resolved nothing!
