Vodacom - Dissappointing and *********

I purchased a contract online from Vodacom in 2013 and they have been billing me for the BBM service since 2014 - meaning I have paid over 12 months in installments for a service I have never requested or used. I have verified my account with them and they insist that this service has been suspended yet I am continuously billed for it despite having upgraded to an iPhone. They refuse to respond to my query despite the operator assuring me that they will refund the amount. When I asked to cancel they requested a fee exceeding R2000. The level of ineptitude is shocking. I would not advise any person to enter a contract with Vodacom - they are unprofessional, *********** and will act as they please without any consideration to the inconvenience or prejudice caused to yourself. I lodged a complaint on the 28 Dec 2014, they promised to call within two days and it is now the 07 Jan 2016. The operators in the call centre are clueless and no help at all. Most of the Vodacom staff are working at Cell C now - if Vodacom had a fair cancellation policy that's who I would rather enter a relationship with. Surely CellC has more integrity.
