Cancel Edgars account

I have sent numerous mails to edg******* as I have requested for my Edgars account to be cancelled. I have gotten no feedback and my account is still active with a '0' balance and now I am being charged service fees. All I am getting is an acknowledgement from Edgars. Why am I not being contacted? Why is my account not being closed? I don't want to an Edgars account because it is no longer interest free. What else do you want from me? It is such an inconvenience to close an account. Everytime I need something I must phone because none of the stores have phone lines. Then I am being told account queries are now with RCS. Everytime I call the consultants cut the call before I can even explain my query. This is clearly poor customer service. My contact details are as follows, email is *** and contact number is ***. I have contacted RCS today and an agent by the name of Nwabisa answered now tells me I need to cancel my account insurance and I will be liable to pay the balance. All I get is pathetic excuses. Edgars wants to charge customers for everything now to recover loses. Don't rob customers for your pathetic customer service
