CANCELLATION NIGHTMARE

What a mess, you require 30days notice to cancel a month to month package, but its 18 Days now since my calender month notice with absolutely ZERO response. I need this over 3 Year old packadge cancelled at the end of november with no further billing - as I have given my 30days notice and it is a month to month packadge. I am not sure if you want the 3Year old router back? But if you do Kindly ARRANGE collection of it in DECEMBER as i have paid for it to work untill the end of November. Kindly ASSIST with URGENT cancellation to be scheduled for end (30th) of NOVEMBER 2022 - THANK YOU
