Vodacom protects ********** transaction

I suspected ***** on my account when a device was loaded to my account, ready for delivery, although I did not do any purchase myself. I logged a complaint and had to send a copy of my ID and 3 sample signatures. Only silence from Vodacom. I went to a local branch and my complaint was esqulated. I had to wait up to 14 day for the ***** Department. Well, it has been more than 14 days since my complaint on 24 November, and no response from Vodacom yet. Worst is that they now have my ID and signature for even more ********** transactions.
