Vodacom ripping customers off

Good day<br> <br> I would like to lodge a formal complaint regarding an iBurst account I had with Vodacom. I opened the account a few years ago and after a while it stopped working, when I went to Vodacom Cresta I was told it was discontinued and was offered a Vodacom modem which I still have.<br> I am still being debited since 2012 for the iBurst modem as well. I was told to call Customer care on *** who were not helpful telling me they could not trace an iBurst account on my account.<br> <br> After being sent from pillar to post between Vodacom Cresta and Vodacom call centre I am still being debited R49.00 I was provided an iBurst technical support email address that does not exist and no one could tell me how to cancel this modem. A lady from Vodacom informed that all clients will iBurst modems were automatically discontinued and was surprised that mine was not. Vodacom is ignoring my query and I need to be refunded for the months I was debited with no device. True to their inefficiency, they are ignoring me yet their response says I will be contacted within 24hrs.
