No response

I have sent several emails and forms of communication to revers a transaction of deposited funds made in error. I was told to wait and phone back, email them proof of payment and follow up, all which I have done but to no avail and/ or success. Kindly respond to my emails advising me when the R2500 wil be reversed back into my FNB cheque account. Sheri-leigh Catherine Baillache-bowes ***
