No feedback from Nedbank on credit refund

On 16 February my retrenchment insurance paid my loan payments but due to the fact that I kept the account paid - my loan account was then in credit. I was refunded a portion on the funds that I was in credit but my loan account remains in credit with over 6K. My insurance has again paid on 01/04/2021, but still no feedback due to the credit amount.

I have even lodge a complaint (on top of the original complaint) and then Jonathan Ndlovu - client service Manager - was assigned to my case on March 17.

I even asked if they could transfer the funds to my vehicle finance account as I am still unemployed and need the funds urgently. I kept my account paid (as per their requirements) but now that the account is in credit you just don't get an answer from them

Please can someone at Nedbank just assist so that I can have this resolved?
