EFT didn't go through

At the end of every month I pay several beneficiaries. This month, Standard Bank chose to process half of the EFTs and ignore the rest. Which means I'm now receiving calls from people who think that I haven't paid them. Which is very embarrassing and can impact on my credit rating. Shocking service. Once again. You haven't had a good year Standard Bank, first you allowed someone to ***** from me and now you don't process my payments.
