ATM CHARGES

I have recently noticed that I have been charged for withdrawals done at FNB atm. When I enquired with the call centre I was told that even tho the ATM has all the FNB insignia and design it isn't theirs. So where are the FNB ATM we can use for free?? call centre agent replies he don't know. FNB is *****ing our money .this has been going on for months, cause it was a small amount I did not notice it. I will be closing my account with them as they are very *********.<br>
