Internet down. No available technical support

I am very unhappy today with Home Connect. My internet was paid Sunday 8am via their payment link. Yesterday I started receiving emails and messages about payment which I understand it can be an automated system notification and it normally takes 2 business days for accounts to receive payment for processing. Now it is Wednesday and now my internet and my tenants internet have been disconnected. I know it is a public holiday but why isn’t there someone on call to render services of technical support to customers at all times. Network services providers and banks always have people on call. Now I have to wait until 8am tomorrow to have this attended to. Totally unacceptable. Home connect kindly resolve this.
