PROOF OF PAYMENT - DIGITAL DEPARTMENT

I called the bank requesting the proof of payment for specific transaction which I was unable to get from their app and internet banking. I started calling in the morning around 10am and spoke to 5 different people from the bank and nobody was able to assist me. The third person and last one, who I believe he was the manager dropped the phone on me. I had a terrible experience with standard bank and until 14h30 when the phone was dropped, nobody at the digital department of standard bank knows how to produce a proof of payment for electricity and I am waiting for them to call or send me the proof of payment since the phone went off and they have allmy details.
