Vodacom Data Bill accumulated due to technical error

<p>Ref: 1- ********** 8614</p> <p>I phoned in 3 weeks ago when I received an sms that my bill is over R2000. I bought a data bundle at the beginning of June and Vodacom never notified me that my data bundle had expired, like they usually do, and apparently I acumulated R1000 of data on my account. Every time my data runs out and Vodacom sms's me, I top up with data bundles. When I went to check my balances, it never reflected my data balance. This is a technical issue on Vodacom's side and I'm NOT paying R1000 of data for a problem on Vodacom side. Someone was supposed to contact me from Vodacom and I've not heard a work back. It's been 3 weeks now!</p>
