Please don't bank with standard bank!

So last week Wednesday i got the wrong details of a person whom i suppose was to pay. I eft the money and it was not a direct payment. 2 minutes later i got a call from the person to inform me that he gave me the wrong details . S rushed to my nearest standard bank branch and asked if they can stop the payment . I was told they can only reverse the payment and it takes 3-5 working days. I filled in the form. Now its more than 5 days later and they are coming with stories and tell me its not guaranteed. So thank you standard bank for losing my money. Id rather switch to another bank . Because you guys aren't there to help me.
