Contact same

So i went to vodacom to take a uncapped wifi line that they addvitze on face book so I got the contract. Only to have the contact for 2 weeks to find out it not uncapped and only 200g of date witch is useless to me I even asked the sales person is it uncapped and I was told yes it is and after 200g it will get throttle to 5mbps up and down after 200g it get cut no date nothing. So I went it to query it to find out I was lie to and if I want I can cancel it for R2500 im sorry this is a complete ******* and a **** and now I must pay a contract that's not working for me thank u vodacom Capetown tokia blue route
