We Tacitly Support Money Laundering

My mother received money into her account on 23 April but has no idea who paid this money into her account. Standard Bank says she must pay R65 to find out and then still wait until 14 May for an answer from Standard Bank. First, R65 is ridiculous for this information, especially for a pensioner. Second, why wait for two weeks? Does Standard Bank encourage money laundering by not knowing who is transferring money to which account? What is Standard Bank saying about its internal controls? Will someone please find out where this mysterious deposit came from and let my mother know. Why must she pay to find out about a deposit she was never expecting?
