FNB - Customer Services non existant

Reversals of payments from merchants are not done seamless and timeously. I was double billed by Ubereats on the 28th of February and they reversed the clone payment of R305.25. They have subsequently issued a refund of the original payment of R305.25. Neither the reversed clone payment and the refund have been actioned by FNB which means I am R610.50 out of pocket. The customer services phone numbers never get answered. I sat for over 45 minutes trying to speak to a consultant to help. It used to be simple to get to talk to a consultant to get a resolution. Now, not so much. It is frustrating to say the least.
