Unsatisfied client

I have been experiencing an issue with my fibre being intermittent for the past month and 2 weeks now. I logged a ticket and I was told that I have to pay for a technician to come to my place and have a look at my device. I am using Frogfoot Air and I’m told I have to pay Vox for them to send out a Vox tech but they are my ISP. I pay my fibre on time but when issues such as this arises it becomes an issue for them to help. We had fibre with Vox last year and the same happened and this year we gave it a try again but nothing has changed. I am very unhappy with their services
