Cancel account

I am so sick & tired of the agents from RCS cotton on busy calling me like i am a ********. I have asked for the account to be cancelled i DO NOT WISH TO CONTINUE WITH SUCH *********** PEOPLE. First month i called and asked for payment options no one was able to help but they kept calling until i was able to pay that was when i asked to speak to a manager/supervisor , i have settled all that is due including the **** calls they made to me bcz with each call i was charged.mind you i have not charged anyone for the calls i have been making to get assisted from them, have you ever begged people to pay them well that has been me😡 i have now settled everything and sent proof of payment but i still get calls and every call the amount due has increased. I NEED THAT ACCOUNT CANCELLED ASAP and do proper investigation see & listen to those records calls and you will understand why i am here
