Please Assist

I've recently signed up with Telkom for their February wifi special. Received package 8/03/19. When i spoke to the consultant who sold the deal promised to send a pre-agreement which i never received, i don't have any contact information or anything to use as in case i need assistance for the router,yesterday i called in 180 to ask if the SIM card has been activated, i then asked the consultant about the router and i was told a different story compared to when i was signing up,20 gig day and 10 gig night surfer,yesterday im told the other 10 gig i'll use it when there's a Telkom hotspot, how is it that i need to ho around looking for a hotspot when i bought a router as if im using a cell phone? Can someone explain to me this mix up?
