Pathetic customer service - international transaction

Good day

I trust you are well. I am completely disgusted as to how my situation has been handled. I have been a loyal client for many years now. I have tried to get into contact with the global centre for more than 2 weeks now. Every time I have been given a different email address. I reside in America whilst still having a nedbank account. I have deposited money into my account from my american account. The money has not reflected into my account. Nedbank has communicated with my american bank stating that I have deposited the money into the wrong account and will therefore be reversing the transaction. I have sent in receipts which state that I have deposited the money into the correct account. Nedbank has since deducted money from the amount I have deposited for my money to be reversed. I do not think I should be liable for these charges as I deposited the money into the correct account. I have asked time and time again for a representative to contact me. My situation has fallen onto deaf ears. I am extremely disappoint with how I have been treated.
