Never make international transaction through Standard Bank.

I made an international payment to a UK institution through Standard Bank, the beneficiary did not receive the funds due to wrong currency of payment because their account automatically reject the payment so the funds got held up in the bank. The beneficiary ask STD Bank to provide a proof of payment (MT199 document) so that they can trace the funds and initiate refund, shockingly STD Bank, a so-called official and reputable bank in South Africa could not provide this document to trace the funds they claim they have paid. I have been to every relevant department within STD Bank regarding this issue asking them to provide the required doc so I can have the funds back, no one has been able to assist, it has been blame shifting from one dep to another. Their International payment dep end up saying they have no means to provide the doc because their system is online, in order words they can't provide a proof of payment for a payment they made. They claim to pay but don't have an international proof of payment MT199 doc, upon that their customer service including their complaint division are absolutely terrible. Can anything be more pathetic than banking at such a bank?
