*******ly ******* by Mondo Mobile into upgrading contracts

I am so angry!!! Again. I got a call from Vodacom on 18th Oct saying she was a direct agent from Vodacom and that because prices had come down they were increasing my airtime and data on two existing contracts and nothing else would change. I was very suspicious and asked a lot of questions, she assured me that there would be no price increase and it wasn't a new upgrade contract. I have now just received an sms saying that my two contracts have been upgraded for another two years and the prices have increased! I am so angry. I specifically told the lady I didnt want to upgrade and was in fact looking at converting to a prepaid. I have found out this wasnt in fact a call from Vodacom direct but from a third party agency called Mondo mobile!!! This is the third time in two years Mondo mobile has **** to me and tried to trick me into taking out a new upgrade contract. How can you Vodacom allow this agency to lie to your customers!!! I am so angry I cannot explain. I want both these new upgrade contracts that have been taken out *******ly cancelled. I am disgusted and appalled at this behavior and the fact that Vodacom allows this agency to continuously lie to its customers is very hard to understand!!!!!!!!!!!
