Very Bad and ****ty service

Vumatel and Home-Connect cannot activate a fibre connection requested almost a month ago. I've been told that it takes between 24 and 72 working hours to activate fibre. Considering there are only 8 hours in a working day, the minimum it takes to activate is five days and a maximum of three weeks. In that time, I can't work and earn an income. Making matter worse, when I cancelled the previous ISP, Vumatel disconnected my services in the early hours of the last day of service on the 31 August. That meant the 31 August I was already disconnected. I am really GATVOL of Vumatel
