On the 19th August 2...

On the 19th August 2024 a sales agent suggested that i test drive their R595 router and i have 7 days to check whether I'd like the router or not..so within the 7 days i decided that rather i send back the router as i couldn't connect it to my PC. So on the 30th i called but i was not assisted at all. The line of my calls was either on mute or calls were not being taken therefore i ended up not getting any assistance. So today on the 1st September 2024 i receive an SMS stating that i need to make a payment for the wifi which is something i didn't agree upon with the company so i don't understand how am i untitled to paying something i did not agree upon on.
