Payfast login OTP not received -ON-***

My name is Grant Ngema and I am an enthusiast of online shopping, esp at Takealot. This morning I experienced horrible customer service when buying a R500 voucher- ON-***.The instant payment system, Payfast, was not supplying me with the OTP I requested to login. I have done this before, request OTP, as I have forgotten my password in the past. I started an online chat with their support person, Zulfa J, who after 43min of failed attempts just ended the chat leaving me hanging. I then called in and spoke to Shane M who promised to escalate to IT and then come back to... I had to call him back. He then insisted that their IT team has reports that I had received and read the 6 OTP emails they sent. Started another live chat with Faranaaz K who basically insisted that the fault was on my ISP even after explaining that I watching the same email account from 3 devices and two different ISPs. Eventually I had to use my work email and nedbank account instead of my primary FNB account (instant transfer from FNB to Nedbank = R40). It was horrible. How will I convince my friends to move on to online shopping when I have experienced such customer service?<br> Screen shots available<br> Grant
