Very disappointed

So I have been emailing Natasha Pillay and Lorraine Masipa regarding my retrenchment cover for my bond which they very effectively sorted out. However, my account has also been debited. Numerous emails for the past 5 days have received no response. Not even an acknowledgment of my emails. Or even just say it's not my dept let me direct you the the right person/department. FNB is always the most exhausting, tiresome institution to deal with. It's not even a year of me being a customer and my word it's a constant reminder as to why I have been and will always be a standard bank customer 20 years in and anything is done effectively, efficiently and without me going into a bank.
