Billing for free product, and still no response

Complaint logged with Vodacom 16 February 2015. Upon upgrading i was offered 24 months free 1G of date, which turns out to have only been a 3 months offer and have been charged since. <br> I have now requested that they pull the recording for this conversation. <br> It has been 6wks, entering the 7th where i have yet to get anyone to call me back regarding this complaint. While all the while you continue to charge me for this.<br> I would like to ask that someone contacts me WITH an answer to my query and not a response to tell me they are leaving a note on the system. <br> The sooner this gets sorted out, the sooner i would like to cancel my contract wit you.
