No connection from vodacom (fiber)

We have vodacom optic fiber in our area. Our property as well as the rest of the neighbors who has vodacom fiber are experiencing endless issues. The fiber works for approx 2 weeks max the entire month and the rest of the month we are without connection. The fiber workers will come and sort the fiber out and for that time only it will work and the next day it will stop working. They will send out they workers out to your at all inconvenient times and make it uncomfortable for you eg they will come late in the evening when it's supper time and then be up and down your lounge. They have also ****med my dad as the contract is on his name. His quite old and don't have much knowledge about these contracts. He was on an active contract and the sales guys that were on the road side **** to him that his not on a contract and made him sign up for a another contract. So he was liable for cancelation fees for the first contract and still they now signed him up for another contract,so there's now no way we can cancel. We have now been without connection for the past 5 days.
