Lack of service

Are you kidding me?! The technician who came to fix my fibre connection completely failed to do their job and left without fixing the issue! Now, when I try to call them for a follow-up, they're not even answering their phone. This is ridiculous. I demand a refund for the service that was supposed to be provided and I want to cancel my fibre subscription immediately. I'm fed up with the poor service and I'm going to look for a better WiFi solution that actually works.
