Incorrect billing

<p>I queried a proposed invoice with Vodacom, early January 2017. The consultant that was assisting me stated that Vodacom has made an error in their billing, she further states that they had charged me a subscription fee for 3 divices and device fee for 3 divices. I further explained to her that i only have 2 lines with vodacom, that it is impossible to b charged subscription fee for 3. She states that she has escalated the matter and Vodacom would get back to me, which did not happen</p>
