Out of bundle data charges??

Good day<br> <br> I've been a loyal Vodacom client for more than 10 years or so and never had any issues or complaints. I'm currently extremely unhappy with the customer service received as my account query is not being dealt with as expected. I've contacted the Call Centre and even visited the Brooklyn branch whereby I was told my account would be rectified and a refund would be done. After sending an email complaint, a response was received and indicated that the additional amount is now for 'Out of bundle data charges'. What confuses me is that this account was always under R400? A block was added to this contract to ensure that the account doesn't go over the specified limit and my daughter uses Wifi services when she's at school. I've never had any additional cost for 'Out of bundle data charges' on this specific account and apparently the invoice for July is also over R900.<br> <br> I'll highly appreciate it if someone can rectify the above matter.<br> <br> Regards<br> MC Allie
