WORST SERVICE EVER!

On the 14 of April 2021 I sent through a form to DebitCardAuth regarding a outstanding authorisation reversal. To date no one from FNB has been in contact to update me on the progress of my query. I have had to call in numerous times with no luck. Today I spoke to Sipho Mahlangu who put me on hold and as expected he just hung up the call. How does FNB suppose we resolve this as your employees have no regard for customers. I need my query sorted out ASAP.
