Standard Bank Mastercard farce

This is directed at Standard Bank's Mastercard Division: You have a system where "suspicious" payments are blocked (in this case, purchasing air tickets) even though you have sent me a one time pin (OTP) which I entered correctly. There is no number to phone to "authorise" such a payment. I was ultimately told, after 45 minutes on the phone to three different Standard Bank numbers, and four call transfers, by a consultant who could speak proper English and had a bit of initiative, that she could not "authorise" the payment, but could "approve" it while I re-did it online. What a complete farce, but thanks to Devonia for ultimately not passing the buck, and for assisting me so efficiently.
