Stanlib slow to react to potential *****

Stanlib has changed their client interface. I use a money market account on a regular basis. It usually takes two days to reflect on their records after I make a deposit into the money market account. I made a big deposit (for me) on 8 May 23 and its still not reflected 6 days later. Naturally I am wary of ***** and phoned the helpline after 4 days. However helpline can only access the same records I can and cannot tell me if they received my money. Stanlib does not allow one to speak to the financial staff, but one is allowed to email them. They may reply in 3 days time. In the meantime some ***** could be spending my hard earned money. The banks warns one of ***** all the time but when one suspects foul play the response from Stanlib has been very disappointing.
