Struggle to close account

Never in my life would I recommend RCS to anyone. It is a forever struggle to close an account. I used to have a RCS account and I struggled to close it. Unfortunately they became the credit provider for Edgars. I wanted to pay my account and then settle it, because I hate RCS. Unfortunately some of my payments does not reflect. RCS is too busy, therefore they cant help me. If I call their employees ask me to send an email. If I go to an Edgars store, they send an email. When I send an email nothing happens. Since they were busy with a transition I gave them a fair amount of time, and even look over the fact that they charge me for calls and letters for something they are at fault. But now I am really tired to wait. Please rectify my account and let me settle it with the first time. I will rather recommend a loan shark before I recommend RCS to anyone.
