Poor service from Evotel and Axxess

I signed up for a 50Mb fibre line thru ISP Axxess and Evotel as the installer, since the day of activation on 03 February 2023 I have been unable to use the service because of extremely slow speeds, after numerous phone calls and tickets being locked I'm still without internet, it's now 8 days later. All Axxess is saying is, a fault has been logged with Evotel and of course, Evotel is nowhere to be found. How can I pay for a service I'm unable to use and seems like I need to beg for assistance. This is the poorest service I have ever received from any company and frankly, i would not advice anyone to use these people.
