Standard Bank - Pathetic Service on Digital Platform

I had a gentleman transfer R1500 from his standard bank account to my standard bank account. This was done using EFT on the 21st April 2019 and to-date it still does not reflect. I had to go to the bank (something I hate as the service is low with queues, at the Sunnyside branch. The system says the money will reflect on the 30th April 2019. Was told that it was due to the holidays and that it must have been a once off payment. This is so totally unacceptable in every respect. So the bank can keep my money for 9 days earning interest for itself, while I wait.
