Standard bank becoming real ****ty!

I'm very disappointed with how standard bank is handling my ***** case I have logged with them I logged a case on march 30th they told me they will be in contact with me which never happened I had to call them to find out what's happened when I called I was told the case has been closed and my money will be refunded within 24 to 48 hours that time went by and nothing was refunded I called again I was again informed that my case was going to be escalated and I will be contacted in 24 to 48 hours it's now been 72 hours and still no one from standard bank has contacted me. In this economy in South Africa how can it take so long for my money to be transferred to my account especially if I've had this account since 2015! It's pathetic and I honestly feel like closing my account if this is how standard bank treats their customers.
