Standard Bank international money theft

Tried to make an international payment, to the same beneficiary I had used before using all the same information (IBAN, account number, Swift Code etc), in fact it was using the preciously saved beneficiary, so none of the details could have changed. The foreign bank say the swift details were incorrect, and the money was returned. Standard Bank just say they can't find the money. The don't help, they keep on saying they're investigating, but you get nothing but appalling attitudes at both the Standard Bank branches and call centres. I am currently minus R450 000. Standard bank is *****ing my interest on that money while it lies in some suspense accout somewhere. NEVER, EVER use Standard Bank for any international payments. They are ***********, dishonest, and they will hide your money and ***** your interest. I have been without this cash for 15 days so far...AND STILL NO SIGN OF IT. ********!
