R99 Airtime *******

I am using Vodacom for my personal & business phones & have loaded R110 of airtime into my business phone,to my surprise R99 airtime was deducted without my consent and when I called their Customer Service Centre I was told that I belong to some Videoshop which I had no idea of,they also promised me that they will resolve my issue within 24 hours and I am still waiting,nothing is happening.I feel annoyed and frustrated by this cause these so called ********** have a business contract with Vodacom to ******* their own customers,which leaves with a big question " What kind of business is the so called Vodacom "
