Cancellation not being processed and don't want to collect the device.

I received the 101 router 27-11-2024 after a delayed of about two days. The day when I received the device already had issues I could connect to the internet I requested a call I was called by number by a number of people trying to assist. They tried and tried but nothing worked. So I was advised by one agent to call a log a call with retention. On the same day I packed the device, logged a cancellation and on rainGo. To this day when I call the call center I'm told someone we call me and never get any calls. I see what you are doing you trying to push me to my debit date so you call bill me. That's unacceptable because I have never used your router because where I stay the coverage is very bad. Can you come a collect you device please.
