Complain for poor service

I am a loyal customer of vuma .i am disconnected without any communication from vuma and this is for the third time. Their watsup line is so poor that you will text them in the morning only to get a response in the afternoon. They dont have a direct line where you can call them. I am based in bramfischer and i know most people who use vuma in their homes will attest to this. This is so frustrating.
