MTN home router

I have been struggling with my home router for the past 3 weeks. Everyday I call MTN and it’s either I’ll be on hold for long till the call get cancelled or when I finally get hold of the consultant, they’ll keep telling me to restart/ switch it off or even move it to a different place and still I won’t have network. The network sign on the router shows that there’s network but I can barely send a WhatsApp text. That time I pay R529 every month for nothing. When I go to the store, I am told to call customer care. As someone working from home , it is really frustrating that I have to buy data while I paid for the services offered by MTN. I’m really disappointed and I would definitely not recommend.
