Nedbank

Good morning. My account keeps on being debited with R5.00 for "Disputed debit order " last time the office of CEO Mr Brown wrote back such amounts. No its back again. Secondly. R10 is debited to my account because i used another ATM becsuse the Nedbank ATM could not work due to technical problems as per the Nedbank tech. My fault? Only Nedbank ATM here at Rifle Range Shell Service station. Please sort the matter out for me. Thank you.
