Frustrated and helpless

I have switch from 4G to 5G router with Rain, the router was delivered of Wednesday. morning, automatically my 4G was disconnected, the new 5G router it doesn't connect to the internet, i have logged about 6 queries on my Rian account, I keep getting the automated reply, to say "help it's on it's way" today now I have not received any call from Rain instead i have been calling them before i can speak to a consultant I'll be on hold for about 18 -20 min with ref ***, i have spoken to a number of consultants, Lebohang, Nikita, Moleboheng since, all promise to have this sorted. Since Wednesday till now I don't have any internet connection and I have wasted so much airtime. I'm very frustrated and helpless.
