Sucking Service

I've had this account for about 2 years now but when I requested to close my account, I was just told that I will be receiving an email. I followed up on this email which I suppose is confirmation that the account has indeed been closed but to date there has still not been any response. I have called the contact centre for 3 weeks and all I get is that the request has been referred and unfortunately, there is no one that I can speak to.

If this had to be a new application, I would have long been provided with the CEO's details if I needed this as my money would have been a concern but because this is not the case and I want to be debt-free, no one is interested in anything, I am not even certain if the account has been closed.
