Wanted to open a business acc at Phumulani Mall FNB , Mokgadi checked my required documents and mentioned that I needed an extra personal proof of residence beside the business one I had. She said I should go and get it and I opted to rather email the credit card statement which I have on email as it has my address and on a banks letterhead she insisted on a bank stamp. How do you get the emailed bank statement to be stamped? It is already on the letter head. But I could feel the reluctance in her voice and that where I decided this not a pleasant and welcome to a business relationship. I blatantly told her thanks not worry am not coming back. And drove to Midrand where Reggie Mashabela gladly accepted my statement and a business account was opened. How many potential clients are being turned down and sent away with such attitude?
