Data disappearing - Exorbitant data charges

<p>On the 31st December 2016 my data suddenly started disappearing. My phone was in my handbag at the time and not being used, by the time i checked my phone I had received and sms to say I have an Out of Data bill of R 601.00, this happened in the space of about 45 minutes. I turned off my data immediately and phoned Vodacom Customer Care - they were not helpful at all and suggested it is a phone problem. No settings had been changed on my phone and again I reiterate I wasn't even using my phone at the time. The consultant said she would escalate it to the accounts department and someone would get back to me asap. I had spoken to two of my family members who are also Vodacom users and the same thing was happening to their data and they had also turned their data off. I also need to add that I had bought an additional 1.25 GB over the 1.25 GB that I get for the month. Needless to say no one phoned me back and I had to contact Vodacom and be placed on hold for over 20 minutes until I eventually put the phone down. I have since phoned them twice more and each time was told my query is still in progress. I then get and sms this Saturday (14th January 2017) to say my query has been closed, no feedback as to what the outcome was. I now phoned the solutions department today (16th January 2017) only to be told that they will not be giving me a credit as I had a data query in July for which they gave me a credit and they only able to give you a credit once in a 12 month period! First of all I have never been informed of that and I was not at fault, if I had been using my phone or changed a setting on my phone then I would pay the bill but I did not. Vodacom hasn't even bothered to investigate where the data was deducted from. On my phone it was from General Services which has no relation to any application? I see ths as absolute day light *******, cause basically if they give you one credit in a year then for the rest of the year they can just do whatever they choose with your data bill and you must just accept it and and pay for it. I have been a loyal subscriber of Vodacom for over 15 years but thankfully my contract is due for renewal in August and I will definitely be looking for a new service provider. I was only asking Vodacom to give me a credit for the Out of Data Bundle amount that I was charged unless they could give me solid evidence for what used my data in such a short space of time. I am really shocked at the level of service and the unwillingness to assist.</p>
