Month-to-month cancelation request

I have had my month to month router contract for more than a yearn Since November, I have been trying to cancel it but am taken from pillar to post. Every time I have to travel from Sub City to Brits, (130km single trip) to have it canceled but I come back with it coz there are always stories like we are offline, no power in the mall, get a POD from courier, etc. I am sick & tired of the failed debit order. I have now left the router @ Brits Mall. I was told to call the number that will forward me the POD but then I was told that I will get it the next day. So am expected to go back another 260km? Please cancel my contract with immediate effect Pls call me on ***
