no response on claim

on 1st February 2022, I deposited money into my brother's account on the 4th i called to check why the money hasn't reflected on his account, but on my standard bank account it shows as paid. i called and i was given a form to fill and i submitted. i got a message back that it will take 3 to 5 working days turnaround time. i haven't received any feedback thus far, today i sent a message requesting the status on my matter, the e-mail was read and still no feedback.
