DISGUSTING SERVICE

As i nedbank platinum customer i am disgusted by the service or lack thereof that i experienced. i purchased lotto online on my internet banking for R50. The amount has been taken off - however when i check the status of my lotto ticket it says FAILED. i tried phoning nedbank on 3 occasions today who put me on hold for longer than 6 minutes each time until my airtime eventually ran out. so here i sit with still no satisfaction. words can not explain how angry i am. i insist on being reimbursed for my airtime. should i not be contacted A.S.A.P you can be rest assured that i will not hesitate to close my account
