Without my consent

A few months ago, I was contacted by a Vodacom representative. Vodacom established that I was replenishing data every month and suggested that I rather make use of a router with an additional 5GB at "No additional cost". I clearly repeated the offer to the representative “At no additional cost?” The reply was “Yes”. (Calls are recorded; thus, the verification is in the recordings). I received the router and now I'm being billed for the device. What’s even worse, the router is probably the feeblest hardware ever invented as the battery life is extremely poor, rendering the product inadequate for my needs. So, now I’m sitting with a worthless router which I have no use for and yet I’m paying a bill every month for unused, expiring data as I was “locked” into a contract for which I did not ask. I still must replenish data the old way up and above paying for useless hardware that I cannot use due to the pathetic apparatus provided. I went into the Vodacom Shop at the Potchefstroom Mooirivier Mall to (a) Cancel a product that I was misled to use, and (b) to cancel another number as I’m determined not to support Vodacom anymore. I was extremely surprised that walk-in service is non-existent as I was told to contact ********** for cancellations. I have contacted ********** just to be provided with another two numbers in order to sort out the mess created by Vodacom. I also discovered that my primary number has been “upgraded” according to Vodacom’s system. I specifically did not upgrade my primary number as I am to move to a cheaper, more reliable and trustworthy provider. When Vodacom contacted me to upgrade my primary number, I specifically requested that the documentation be forwarded to me for scrutiny before I’m ******* into being locked into yet another contract that I have not requested. Well, surprise, surprise! Vodacom did it again and without my consent “upgraded” my primary number. So, with all three Vodacom numbers I now have trouble and there is no one-stop service that can assist me. Shame on you Vodacom!
