Paying month after month for something I don't have

Again as always, Vodacom has still not delivered the product I am paying for. Because of their bad service I cancelled my contract and at the cancellations they made me an offer to keep me as a customer. After accepting the offer which I on the account I wanted to cancel, they proceeded to take my money month after month for a product I still don't have, even had a nice lady phone me to promise everything they would eventually still not deliver. but to take my money they have no problem with, that they can do very well with no issues at all. you would thing a company as big as Vodacom would not ***** from people but then again, what can we expect, part of a ******* country so they just joined the gravy train - free money and nothing in return.
