Total *******

Good day I have a contract cell phone with Vodacom and when I paid R369 per month and it then went on to R500 Per month I would had airtime as well as 2g on the contract. Sometime in June last year my debit amount was changed to R668.99. Last year in September they then changed it from 2g to 1g and when I queried it was put back to 2g. To my dismay in February they only offer airtime on the first of every month and no data and countless phone calls later where a consultant mentioned that the offer has expired and could not explain why. Waiting for someone to call me. To pay R668,99 per month on a contract and receive no incentives is shoddy service indeed and a *******. I have been with Vodacom for over 16 years. I should change my service provider. After sending this to Vodacom a consultant and phoned me and told me they would listen to the conversation and tell me if I had opted for 3 years update or two years. The consultant assured me on Monday 11 April he would let me know and conveniently on Friday last week I did get the 2g but on Monday I got a reply from Vodacom that I had agreed on 3years without letting me listen to the conversation. Then today my debit order has been changed to R701.97. It is a total *******. I really am so irritated and want to cancel my contract. I am currently using Rain data and they are so affordable and you do not get "hidden agenda". I want to listen the conversation where I agreed to 3 years update. Please help properly. Do not ask me to call a consultant as they are "useless". I need a response immediately.
