Unsuccessful money coming abroad.

I lost business abroad , as my cliant sent money to my business acc , and it was blocked by FNB for a sender to change beneficiary name, i called FNB and after LLOYDS bank have changed the name , 2nd time i called they told me they havnt got any on from lloyds bank , and LLOYDS has ensure my cliant that they have changed and also communicated with my bank here in SA. When i called for a 3d time to.check what is happening with the funds i was told they reversed the money back after a month of ups and downs , and they never even made means to call me and find out what is happenig, they never made any means to communicate with me . Now i lost business and my cliant abroad does not trust my banking system and it also cost him a lot to change the currency and the charges he had to pay, an he mite also be charged as the money is reversed. Very dissapointed.
