Depleted Data

I've been waiting for a week now for a response. I actually refuse to take interest in any ongoing investigation, an investigation which can last a week or few days, who knows. I can't wait that long as I need data asap. It was easy as 10 seconds to load my data and just as easy to deplete it at once so surely it should be easy to replace it. All I'm kindly requesting is for all my data bundles to be returned. The depleting of my data is actually tantamount to Vodacom *****ing money. I own an iPad for which I buy monthly 1GB data and all along this lasted me over a month. On 14 August 2015, I purchased 1GB, it was gone within 2 days and I did not even use it as I used my iPhone for the internet. Friday, 11 September 2015, I bought another 1GB but used the Cape Town Slow Lounge Wi-Fi(you can check my records if you want) to do all Apple Store updates. On 13 September I was surfing the net and told data is fully depleted. I only browsed twitter and facebook, and even then it was also partly on my phone. Kindly return my 2GB of data cause this is unacceptable. My iPad number is ***. Please also notify me once its returned. Thanks.
