Edgars refuses to close my account!

Edgars does not want to close my account, at first they sent me confirmation that the account is closed but later on I received a statement for service fees, I paid it as I saw that the billing date was prior to closure confirmation. This month I received a statement for service fees again, when I enquire this, they informed me that they are closing it, when I enquired further they requested account details, but they had sent me confirmation that they closing it. I asked which account did they close if they are only requesting account details now, of which I did send initially, I have not received any feedback.
