Disappearing airtime - we are getting **********!

<p>Can Vodacom give me an explanation as to how airtime that was purchased, for R29, suddenly disappears while driving 170km, not making any calls? On arrival, I purchased the power hour, but noticed that my airtime was already R5 less (not taking into account the purchase for the power hour!) Since then, i have not made any calls, purchased another power hour, and 2 days later, i have only R1 airtime left! All this in a phone that has data on it, with all background activities restricted! The data does not diminish, but the airtime does!</p> <p> </p> <p>This is not even the first time! When i first noticed this, I called Vodacom, and the operator told me to disable "WASP" services. I told her I was not subscribed to any of those, but took her advice nonetheless. I sent a "stop all" sms to their number, and twice I got the response that I was never subscribed to those services...as I knew I wasn't.</p> <p> </p> <p>Now I am still experiencing this sofisticated form of thievery, after having been a loyal contract customer for 13 yrs? This is grossly unfair! </p>
