Ashamed of Vodacom's sales misleading of loyal customers

I am very disturbed by Vodacoms misleading of customers. I was called by a sales agent, advising that Vodacom will be migrating me to a new plan without any extra charge. I asked them to reiterate and they confirmed that there will be NO ADDITIONAL CHARGE. I agreed, and the very 1st month thereafter, Vodacom adds an additional R275+ to each of my contracts. Nobody seems to be able to assist me with identifying this sakes agent, or to reverse the entire migration. This is an ******* migration, yet Vodacom seems to be taking it so easy
