Dissapointed

Got unlimited fibre with Vodacom and it's not working for me. It keeps dropping, I can never stream for more than 30min and it'll be down for hours. I've called them several times regarding this issue and there seems to be no solution. They said they'd send me a technician to assist and they haven't. I suggested that we cancel the contract and they want me to pay for the remaining part of the contract which is 23 months...that time I've had issues from day 1...why should I be forced to pay for a service I'm not enjoying 🤷🏽♀️
