24 Hour Promises FNB

So I logged a complaint at Hello Peter on 12 May regarding a refund from FNB for covid-19. ref no: ***Q - Covid 19 Cashflow Relief dd 7 May. I also received a ref from Loans Ref ***NF both promised to refund within 24 hours. Both on 12 and 18 May. I did not receive the refund and mailed them again - no reply. I messenger RB on FNB complaints who said he referred my case to the relevant departments but have not receive feedback. Today I received a mail saying they have received my mail of the 18th but it will take 3 working days.......so whats next??/ Will they send me a mail saying sorry again (for the 4th time) and again promising to refund within 24 hours? Will RB of FNB Complaints reply to my messenger??? By the way is there a person who is doing the admin job on the FNB complaint facebook. There are quite a few complaints and no one responding from FNB.
