Telkom service is BAD

I am currently in a 24 month LTE contact with 7 months remaining. I want to change to a fiber contract and requested to cancel the LTE contract. I was told I need to pay the full outstanding 7 months of the contract even though I wont be using the data and also pay R800 cancellation fee. That is R2893 before I can switch to fiber. I have been a Telkom customer for almost 4 years but I think it's time to move over to another service provider. Their service is appalling! The consumer act clearly states that a consumer may cancel early and be charged a fair cancellation fee but it may not amount to the full remaining installments.
