Ongoing frustrations with Vodacom's service

<p>I am writing on this website as calling the Vodacom call centre is not effective. I received a call from Vodacom advising that I upgrade my current package due to my package not being sufficient for the amount of additional data and calls made. Being very sceptical due to ongoing problems with Vodacom, I finally agreed asking what the upgrade would cost me in total and if I can revert back to my old package should I change my mind. Off course all the answers were positive and I agreed to upgrade. With the first bill I could immediately see the increase in my bill and asked them to revert back to my old bill as they promised that the upgrade would be more cost effecient. They agreed to revert back to my old package. I received an e-mail confirming the changes and was requested to pay R678 to pay for the changes! No where in any of my conversations did they mention this. I immediately responded demanding that they revert back to my old package without any additional payments and have not heard from them again. When I checked my account this morning, they conveniently added the R678 to my bill to pay! I do not know what to do anymore as I have had too many unpleasant incidences with Vodacom in the last year after being with them for more than 10 years. This will be my last contract with them</p>
