No contact, desperately in need of replies.

I have tried all methods of contact but to no avail. I have my services scheduled to cancel on 31 August 2024, I have sent requests on the app that never gets a reply, called the customer care number that after 5 minutes or so wait gets disconnected every time, hopefully I can get a reply here, how long does it take to collect the router? I have paid my last premium now in August (also I saw I have been overcharged insane amounts on the first 2 months) I need the router to be collected the soonest possible after the end of my services, as I am moving. ( i need to mention that I received a message that due to inflation the price has gone up - it doesn't affect me as my services end before 1 September, but should you not get permission from your clients before you take more money? And maybe get the connection better before hiking up the prices?) Anyhow, please advise how long it will take after the date of cancelation, because of the fact that I will be leaving to another province. And also when will someone contact me because of overcharging me 2 months?
