Angry and disgusted

I'm appalled at the service that I've been receiving from standard bank. Absolutely disgusting. In April I was asked to block my card because there were *****ulent transactions that kept going out. 1stly. Let us keep in mind that I work NIGHTSHIFT it took me 2 days to get a hold of an agent on the app. I couldn't wait! I needed to sleep! Eventually on the 13th of April I speak to someone on the chatline who advised me I need to have the card blocked in order for them to do an investigation and in the meantime I can go to the branch and get a new card BUT I HAVE TO WAIT 12 DAYS FOR FEEDBACK FOR THE INVESTIGATION. I go to the branch, get a new card and I'm told at the branch that they cannot help me on a refund I have to wait for the ***** department. Since then, today being the 21st May, I have not received any update. From the app I'm on the phone and I'm back and forth and mind you! I'VE COME FROM NIGHTSHIFT! I'M EXHAUSTED!!!! I get told that a claim was only put through LASTWEEK by your agent Musa today and then he transfers me to another department where Nandi tells me that I HAVE TO GO BACK INTO THE BRANCH. How are you guy's dealing with this? How do I go into the branch again? When do I sleep? Why did they tell me at the branch that they can't help me and then the call centre sends me back to the branch? Is it just because my refund is small that is why I'm being treated in this manner? Ladies and gentlemen, this is a small amount to you, but I would expect this in my account today please. The reference number given on the 13th April is: *** and I can be contacted on ***.
