*****ing money on bank charges

I was offered a nedbank platinum savvy cheque account in may which i took, with this account i am suppossed to have unlimited free withradwals at nedbank atm and thats what i signed for. I realised that nedbank has been charging me for nedbank atm withdrawal charges which is not what we agreed on. I contacted the call centre and they advised me to go to the branch to have charges reversed and i went to bloed mall branch and they told me they cant reverse those charges as they are correct, i explained to them about benefits of my account but they insisted those charges are correct. I contacted the call centre and explained what happend but they said only the branch can reverse them. I went to centurion branch where i opened the account and the team leader said she can only reverse for 3 months, i asked her about other months and she asked me why didnt i look at my bank statement and come earlier, i openef my account and signed for a service they promised but now i am supposed to police them amd make sure they dont take money hey are not supposed to take. Dear nedbank please give me my money back, i cant always draw statements which cost money to take to the branch to try get my money back only to ne turned away. The charges in question has reference atm/ssd fee
