Edgars account

I am appalled by the customer and financial services i have received from edgars.Since September 2020 it has been more than a challenge just to close my account.The amount of time and airtime i have spent is frustrating.I was asked to pay an overdue amount based on club fees which i never signed for.No one could really help and was pushed around from one department to another.I had even spoken to a sales manager and after sometime was told that my account is closed and that i would even get a refund for my payment,which i am still waiting for.I had to send proof of payment and was told on their side everything is cleared and that my account is closed.I have just received a call to say i am overdue?on what exactly?
