Data Bundle Billing Disaster

I am currently on a package which comprises 1G data per month,at a fixed cost of R430 .Over the last 34 months that I have been on this package, I have always consumed way below this limit as I very rarely use my cell phone for browsing or downloads.<br> <br> My November invoice stunned me as I was charged R3520 for data usage, with a whopping 1.8 G used just on 1 day (18th November),which attracted an obscene cost of R3014. A preview of my past usage will show that I average about 10-20 MB per day as I use my laptop for browsing and downloading. I was informed by the call centre agent that possibly downloads were taking place in the background, without my knowledge, due to settings. I am not a tech savvy person and use my phone predominantly for making calls.<br> <br> I was given a service request no. A1-XF62-7V5ZA on 16th December informing me that I will be contacted within 14 days once the audit was completed. My main concern is that I will be billed this massive amount on the 28th December and then my debits with other companies will go unpaid. This is a huge injustice for someone who has diligently paid his account every month .<br> <br> I humbly make a request to Vodacom to sort this issue<br> <br>
