Poor customer service

I have moved out of the country and it has been extremely difficult to reach FNB. On the 6th of May, I arranged with a FNB banker to contact me to put me through to Collections. I was speaking to the lady for about 30 minutes, explaining my situation and what we can do going forward. She explained that she will speak to her manager and they will email me due to the time difference and difficulty reaching me. That was the last time I heard from her. Also, I can't find any email address for them, so don't know what is happening now. Can someone please contact me via email as they promised as FNB always say they try to reach me but I am not receiving any phone calls from them.
