Account settled but Wesbank Cashpower won't close

In an attempt to close an existing Wesbank Cashpower loan, I have been transferring money into the loan account. This was relatively easy as this was merely a transfer on my FNB banking app between accounts.

After numerous transfers (with the capital balance decreasing). I requested a settlement letter on the 7th of June. The Letter indicated a settlement figure of R790.67, I made the final payment.

The transaction statement from the Wesbank website shows all my payments but now i'm being asked for Proof of Payments. Something that FNB cant give me for transfers.

Its been a nightmare trying to close this account. The call center is of no assistance.
