Worst worst non-service RECALL department

i was transferring money to my sister’s Standard bank,but I mistakenly missed one digit..logged a recall with my branch at Irene Mal(extremely helpful) and was informed I would then communicate directly with the Recall department on email, followed up on Tuesday, the 16 November. They only responded on the 17th November, the email they sent says it’s encrypted I am unable to view anything..I called the call Centre which is obviously useless,sent numerous emails to the Recall department,no response.Please assist, the service for this Stupid department is extremely. How possible is it that there’s no direct contact for them?Nedbank will need to review this,I’m absolutely disgusted.
