Disconnections

I recently joined the Vox telecoms network now in August. There's an issue I realised a week from the install. The wifi keeps on disconnecting for a few seconds and then comes back up, I called and the said nothing was wrong and did a speed test. After a few days the same happened and I called again, they dispatched a technical team and they changed my Connection device and still.after they left the disconnections continued. They then said it might be the Fibre provider but I'm really tired now. Every day there's a disconnection and somehow they don't see it. I don't know how many times I have called them now. I'm really dissatisfied with VOX!

My wife and I always have issues when we're in meetings since we work from home and it's really unnecessary 😑 I wish I could just undo going with them
