No response on lodged complaint 04/09/19

I lodged a complaint on the 4th of September relating to what I felt was false information given to me on the 23rd of July regarding slow lounge access at OR Tambo. My reference number issued on the 4th is ***. To date I have had no feedback. I have called in twice to discuss my matter and on both occasions I was assured that someone would get back to me. I am annoyed as FNB are taking far too long to investigate my query and it is not good customer service that I need to keep following up in an attempt to get feedback.
