Still awaiting feedback on query from branch

Around the beginning of September this year I made a withdrawal of R 3 000.00 at the FNB ATM at N1 City Mall but never got the money since there was a problem with the machine. A reversal was done immediately for that amount on my account and I withdrew the amount of R3 000.00 at another FNB ATM again which I then got. I later went to Checkers Hyper in the mall and made yet another R 3000. 00 withdrawal. On the 24th of October when I got my statement I saw I was charged R 129.65 bank charges. Long story short went to N1 City Mall was assisted and a query was logged for the bank charges where the consultant that assisted me confirmed I was overcharged. Was promised that I will get feedback . Haven`t received any so I went to the same branch again about 2 days ago. Was again told I was overcharged for the transaction made at the ATM.Explain the whole story again, gave my details once again ,was promised to contacted , no feedback.I would really advise all clients to check your statements for discrepancies like this
