Sunday down time

EVERY Sunday it is the same thing, the internet is slow to dead. We can not phone megasurf at all, and the owner, whom I have sent a whatsap once, gave a rude answer and did not want to help. Add the fact that there are rumours about him making money from this issue via the sms fault reporting, and you get a bad business with bad service and reputation. Get out of the vaal to make space for other ISP's that want to actually deliver a service?.????
