Standard Bank consultant not doing what they promise over the phone

There's an unauthorized debit order which went through on Tuesday morning, the 27th of November. I then called standard bank at 8am on the same day for them to reverse this debit order. I was assisted by Amalian who said to me because the Debit order went through on the same day I want to reverse it, I'd only get it after 48hrs which ends today. She gave me this reference no. ********** 950 and said I will get the money early today. I haven't received the money back to my account and this is not the first time this happens, 2 weeks ago I went to the festival mall branch in Kempton Park for a reversal and and put me on a call and turned out the consultant who was assisting me over the phone didn't do the reversal. I had to call again for assistance. Standard bank consultants are so ***********. Please deal with this issue ASAP as this money wasn't even mine and I need to give it back to its owner.
