Scanning in of documents

I urgently needed R3000 by 08/01/2019. I called my standard bank on Saturday 05/01/19 and was told that only the sales department would be able to assist and they were only available in the week. I called them at 8am Monday 07/01/19. I spoke to Ms Shari Boys only for about 2 minutes when she advised she could only processes my request to increase my exhausted revolving credit loan from R15 000 to R18000(I hadnt even discussed these amounts yet), if I emailed her my last 3 salary slips as I work for government and get a housing allowance. As I am on holiday and went on leave before receiving my December salary slip I could only send her pics of the September, October and November salary slips. I waited for about half an hour without a reply and called the call center again. I waited another 10 minutes before someone answered. At this point the person answering the call advised that Ms Boys was on another call and would call me back. I never received a call back. Then I got an email from Ms Boys saying she needs PDFs, so I converted the photos to PDFs and resent the email. Then after about another hour she responded asking me to scan in my 3 months salary slips. I advised that I was on holiday with my 1 year old and my 2 year old and did not have access to a scanner. After about another half an hour without a response I called the call center again. I was on hold for about 30 minutes before someone answered. It happened to be Ms Boys, who rather annoyedly said that if I app**** for an increase in my revolving credit loan or an over draft, she still cannot process my applications without scanned copies of my salary slips. After my disappointment with standard bank. I app**** for a loan with Wonga. It took me 10 minutes to apply online and all they needed was a bank statement, which I downloaded from my internet banking app. I was approved within 5 minutes and received payment in less than an hour. How is it that my own bank cannot see my expenses and income? Why do I need to scan copies of salary slips? And especially scan??? In this day and age? Who walks around with a scanner? Ridiculous. I am so disappointed in standard bank. I would have loved to keep all my business consolidated with standard bank.
