Proof of account settlement

I was reading an article now about the difficulties that people are experiencing in closing their Edcon accounts. My account is reflected as "active" in my credit profile and I have, on several occasions over a period of more than a year, asked Edcon for a proof of account closure, or to inform the credit bureau of the status of the account. However, I am told a lot of stories about how customer accounts were split between or handed over to the Nimble Group and RCS. Both parties claim that they cannot any record that I have ever had an account with Edcon.
