Sickening Service

Every two days Vumatel has disconnected our WiFi and each time I had to wait in a queue to contact our service provider to log the same fault. No one comes out to check or repair but mysteriously the WiFi is restored after being the 19th customer queueing to log the query. I am paying for a service that on a monthly basis and I am left without WiFi? I want a refund for the days I am disconnected and I want to be able to use my WiFi today.
