SR*** fibre Vodacom no internet everyday issue

I am paying R1200 200mb up and 200mb down for 2 years for Vodacom fibre and I started experiencince inter connection issues for 2 weeks now everytime from 9pm till 9am and I have logs to prove and I logged a ticket with all details and every time when I call in, they do temp fix to date. I always ask to speak to network engineer and they tell me we cannot guys I am feed up and here is my service request SR*** it's a **** service guys.

They called in Vuma technician and those unprofessional guys they bumped my garage with their car and forced to change fibre cable where the issue is on the ISP.... nonsense ****.
