Vox - very poor service. Stay away

I have had a Vox fibre contract for about 3 years and would not recommend them to anyone. Every time I had an issue, I could never get hold of them telephonically and whenever I got through, the call would always cut off and queries would not be resolved. The whatsapp bot is also not helpful in sorting out queries. I am now trying to move to another ISP and even though I cancelled in time and stayed through my 1 month notice period (which lapsed 6 days ago). I cannot move to another ISP now as Vox has not released my line. I am now on day 5 without wi-fi due to this and am forced to use Mobile Data to work from home (my wife also has to use her mobile data as she also works from home)
