MISLEADING SALE - MOBILE TALK

I was phoned by a mobile talk agent regarding a new LTE contract. I was told told in NO UNCERTAIN TERMS that the line would be uncapped or an OPEN LINE , at speeds of over 90Mbps, could connect at over 30 Meters to over 2 and would cost me R499/pm. I asked numerous times if the line was definitely uncapped & the agent said YES. Since this was a better deal than my current uncapped ADSL line and being a mobile service offering I obviously took the deal as it was a no brainer. As I was going away in December I thought it would be sensible to activate the offer in January - I was told that the account would be activated on activation of the SIM card - ANOTHER MISLEADING ISSUE - when I called to activate it was apparently already activated....to mu surprise - we queried the data situation and discovered that it was in fact a capped line of 30 GIGS - not what was sold to me AT ALL! There is no need for me to move from an uncapped to a capped service - shock horror! On requesting cancellation I was told that I was out of the cooling off period and would have to pay a cancellation fee - which I am still waiting in anticipation for......please beware!
