POOR SERVICE FROM NEDBANK

I AM UTTERLY DISGUSTED with the service from Nedbank. On the 28th I was was charged twice at store I then checked my statement it was shown that payment was only taken once by that particular store, I then contacted the customer care and was told it should reflect on my statement within 3 days and I should take my statement and go to store they will then refund me. On the 5th day I call the call centre AGAIN only to be told that by the afternoon it will reflect statement and nothing reflected on the 8th day I called back and they told me my money will be deposited back into my account on the 11.11.2023. Today being the 13th day I call the customer care again and they say that they cannot refund me now I will have to wait it's a long process. WHAT KIND OF BULL**** SERVICE DOES NEDBANK PROVIDE. I WILL DEFINITELY BE CHANGING MY BANK AND I WILL MAKE SURE TO POST THIS ON EVERY SOCIAL MEDIA PLATFORM.
