False details on deals

Very disappointed with Vodacom fibre deals. I'd say a sales agent was only interested in making her commission and gave false advert to attract customers. "Get vodacom fibre deal on a special price R350 for 2months thereafter you will pay R499, ON A MONTH-MONTH deal, if you not happy with the deal you can cancel." To my surprise that was not true. My contract was active from the 22nd of July, when i received the statement its now billed R708. I call to get clarity I am now told of a delivery fee for the router and 1 month discount and not the 2 months i was told about in the beginning." It happened that I have to move from where I was staying as of the 7th of August, I call and asked to change address, I was told my new address doesn't have coverage, to cancel the fibre and opt for LTE i was told to pay R2000+ for cancellation. The sales agent when she was making the sale, she said you can be moved upto 3 times. Very much disappointed by vodacom, their sales agent she tell clients everything and stop keeping information behind in the name of them making a sale.
