Funeral pay out ERROR

Good day. I am normally very happy with Capitec Bank. I am writing to you with regards to the funeral policy, which was paid out today, very promptly. My issue is, during the claim process on the Whatsapp platform I indicated that my FNB account should be used for payment. It confirms they will verify if the account is yours. The amount was paid into my Capitec account and there were debit orders that came off it, which I was trying to avoid, as this is for payment of my mother in law's funeral!!!!!!!!!!! I phoned and was told they can see i asked for the FNB bank payment, but should have sent them a proof of account. NOWHERE was i asked for this. They emailed me about a document which was short, but not a proof of account. Now, I am in a predicament as apparently the funds cannot be reversed and paid to FNB. So, Now How am I going to pay for my Mother In law's funeral service? Surely, this is not my fault, surely Capitec needs to sort this out. When I saw what is happening, i transferred R5k to the savings part, so that that is also not taken.
