OTP system is pathetic

I tried to use some of the ebucks that I accumulated on my account for a purchase on [URL Removed] however, the OTP takes so long to come through that the transaction times out every time. the lag between requesting the OTP and the time you receive it is unacceptable, especially since when you change to Card payment and use the discovery card to pay, that OTP comes through instantaneously. Why the lag for Ebucks when both platforms are managed by FNB.<br> There is so much hype about the Ebucks rewards programme via advertising etc. yet when you want to spend the rewards it is a mission.
