DSTV internet call centre non existant

I have struggling to get someone to call me for fibre connection for 2 weeks now. I have sent sms, whatapp, called but no one gets back to me. I called again today and the first consultant put me on hold for no reason for 7 minutes(I want to know why this happened). The second consultant gave me a number to call only to find out that he gave me the DSTV whatsapp number. Why do I have to beg to receive a service that I will pay for?
