Dynamic Portfoloi bad service

About 2 months ago, money was deducted from my mother inlaw's telephone. R127 of airtime was deducted *******ly. This was reported to Vodacom's ***** department, and of course no responce. We contacted the company through which we load the airtime to the phone. Dynamic Portfolio does not come back to us regarding this issue. If you ask about this issue, no body has any answers. This is totally unacceptable.
