Terrible service from your staff

Dear fnb, I would like to assume that when you assigned Sibongile Mbiza and Tumelo Ntlha to assist me with my banking your intention was to improve your service. Unfortunately this is the worst experience I have ever had with fnb after so many years of banking with you. Your staff never replies to emails. The last email I sent them was on the 21st July 2018 and they have both never bothered to reply. I have raised this issue with both of them before that they never reply when their assistance is requested but I am still getting poor service from them like they are donating their time to fnb. Fnb will you assign me a banker who will at least do their job.
