Telkom Fiber

My husband signed on with Telkom fiber. They told us it was unlimited at a speed of 25 download and 5 upload with no FUP for R399-00 We do not even get 3 download and they changed the contract without notification or permission. They put the price up and no longer unlimited. They tell you one thing and then do not keep to their promises. They tell you anything just so you will sign up.
