Disappointed

I Transfered USD to the US. After a week I get an email saying the transfer was not successful. The email came from Buyi Luvuno. I have sent many emails and left messages for Buyi Luvuno confirming to refund money back to my USD account.it has been over a week now and have not had a response from Buyi. I have been banking with FNB for quite long and had no issues until now. I have recently also open an account for the company I work for as well. It is sad that an employee of FNB can have so much power to hold back funds and No one else can assist. Service is very important to me and this is not the way it should be handled. I'm I going to get refunded with interest or I'm I going to be charged for FNB handling my transaction. There are many new banks opening and this is not the way to keep or get new clients. I have still not received a call or email from Buyi.
