Investec In-App Authentication doesnt consider payment gateways

Investec launched their new 'secure' in-app authentication protocol - but dont consider any online payment gateway. Now they say 'sorry' - but dont rollback the new release. No-one who choses to bank at investec can use Takealot, Snapscan, Zapper, Payfast or any digital gateway. Did Investec really not think about this? Embarrasing!
