Payfast and bank account details

I transacted a payment with PayFast. Then i realised that they store all my banking details, including the CVV for my credit card. I have tried endlessly to get them to cancel my account and purge all my banking details. That was on 21 May. They have simply ignored me and *******ly debited me on 18th June. The very scariest part is that they bypass the Verified by Visa protocol by some underhanded measn of getting the message to themselves. I shall be taking that up with FNB. It is absolutely not on that a third party payment service provider mau be allowed to retain such info. If they get hacked every custoemr is at grave risk of massive *****. Many years ago i used to be involved in the inter-bank payment systems. If these are the new rules of engagement then the banks have declraed war on their own clients. An enquiry to PASA was met with silence, not even the courtesy of my taking a job with *** and travel. So BEWARE, if you are using PayFast you are seriously compromising yourself.
