STANDARD BANK ELECTRICITY DEPARTMENT ARE ******!!

I am totally disgusted with Standard Bank electricity department. on 14th April 2022, I bought electricity for R1,100 using internet banking. The transaction did not go through I got a system error message. I did not get the recharge pin either. A few minutes later the R1,100 was returned back to my account which proved that I could not buy electricity on their system on that day as their system was faulty. I moved on and bought electricity elsewhere. Two weeks later, on the 25th April, standard bank deducted the R1,100 from my account for the transaction that failed on the 14th of April!! I phoned them and had to be sent from pillar to post explaining my story to different consultants. I was eventually promised that I will be refunded my money by 17:00 today 28 April as they are aware that their system has been having errors. Now at 16:45, 15 minutes before I am suppose to get my money, another standard bank consultant calls me asking me to narrate my story AGAIN and say whether I did get a recharge pin on the 14th April. I AM SO DISGUSTED WITH THESE PEOPLE WASTING MY TIME AND BASICALLY PLAYING WITH MY EMOTIONS. PATHETIC STANDARD BANK PATHETIC!! I WANT MY REFUND YOU ******!! The case reference number is ***. I do not want another call from standard bank I want my refund
