Non-Instant money sent for instant money service from Standard Bank

I sent instant money on the Standard Bank application to someone who is in Cape Town. The person is in distress because of the covid 19 lock down. They have not received the voucher 24 hours later, even if Standard Bank calls it instant money. How ironic. It is not the first time, in the past it has happened about 3 occasions, I had to call at my expense order to have the sms with voucher number sent. How, atrocious and bad service. I almost feel like moving all accounts I have with Standard bank.
