FNB refusing to refund

FNB giving me a runaround with a refund. Closed my Lona account with them on the 27th of October and Hyphen made a payment to them after the account was closed on the 29th. They asked me to send them proof of payment of which I did, but now it’s not enough, how, I don’t know. This is very tiring, I just need my money back, R1560 for someone who just got out of debt review is a lot.
