Instant Money Service - Not instant at all

Yesterday, I needed to urgently send money to someone so I tried to use the Send Instant Money feature offered by Standard Bank from my business account. Filled in all necessary details, clicked done, got confirmation that voucher had been created. Then nothing. Recipient waited and waited but got no SMS with voucher. So I checked on my account and the money had been deducted. After waiting half an hour, I called the bank only to be told that because this is the first time I am using this service on my business account that there will be a 2 hour delay and that they can't give me the voucher until this 2 hour window has passed! Um, what part of "Instant" do you not understand? This defeats the whole point of this service. The worst of this experience is that there was no warning or information message telling me at the time I was creating the voucher that there would be a delay. No, I had to waste my time double checking all the details to see that I didn't make a mistake and then call the call center wasting my money on telephone calls to find out what should have been told to me upfront by your app. Had I known upfront that there would have been a delay I would not have used the service in the first place. This whole experience has been extremely frustrating and has cost me money due to Standard Bank's sheer incompetence. I think I'm entitled to demand a refund of my account management fee for this month as why should I pay for services that don't do as advertised.
