FNB refuses to reverse ********** transactions

FNB refuses to instruct other bank to reverse a deposit to it's client, even though other bank requested FNB to do so. I request an a mount of 4200 to be stopped for withdrawal by Standard bank as I suspected the receiver to be a *********. Standard bank agreed and said they will wait for FNB my banker to instruct them, they even sent a communication to FNB which FNB also confirmed to me, but they never sent an instruction. This happened on 13 September 2018 and up to now I never received update from FNB, not even a response to my emails that I keep sending. To me it seems the bank that is concerned about this is Standard bank which I don't even bank with, because they have been asking if I still want this money to be refunded but FNB is sitting on information, I gave them everything they requested (an affidavit and the case number). The email they gave me to ask for an update "Triegaardt, Samantha" ********** only gives me an automated response.

So disappointed!
