No after sales service

No service from vox. Same question I asked you guys last time. Do I need to get my settings "optimized" or "reset" every week? Last time vox sent a Tech out . He "optimized" my extenders. Vox then was going to get Evotel to check the line . Vox phoned me numerous times to ask if Evotel came back to me where i responded NO. Then suddenly i got a missed call from Vox. Next step they said they could not get hold of me. When letting the phone ring for one or 2 rings that's not a call. Thats a missed call. Also, no call after that? Ticket was closed. With NO feedback on what the issue was and when it would be resolved. This week I'm just gatvol for vox. Paying the fiber but can't even stream. Can't even watch Tiktok on my phone then message will pop up saying network unstable. This is what I reported last time with still no resolution. Are you guys just to lazy to help? Just let me know then i will cancel my service with vox and move to someone that actually wants to help me.
