payment made to a paid up account

Hello, <br> <br> I have a loan account with Nedbank Loan: *** and it was paid up in last year September already and there was even a paid up letter from nedbank that was sent through to octogen. <br> <br> Yet octogen has still been paying this account which is no longer in my name but another clients name, I want this mess sorted out and management to contact me from octogen and i want a refund for all the payments made to this account that was closed in my name. My ref for the query logged at octogen: Your reference number for this query is #66167.<br> <br> I am so upset to think that i have been paying someone else's loans. I sent through the paid up letter as proof to Octogen. <br> <br> Please get this matter resolve and revert ASAP and also if you cannot reach me on my cell phone please email me.
