Dissaponted by Standard Bank

<p>On the 30th May. I called Std bank and requested they pls reverse 2 debit orders for me that took place on the 26th April 2016. Which the lady that assisted me said she has done so and the money will be available on my account in 0 to 24hours. There is still no money that was reversed. Sondo i have to fall again and wait for another 24hrs?</p>
