Poor Customer Service

On the 25th of February there was money which was taken form my account of R399 without my authorization , eventually i called Nedbank Customer Care and spoke to the a guy by the name of Keagan , call *** , the guy advise there is no record shows in the system but he will request a refund. i advise him i never buy anything from these people Shaw Course Shaw A. the following date a called again cannot remember the lady who was assisting me. but she advised there is no refund processed and the amount which was taken from my account is is not a debit order but its a subscription. i advise her i don't know who is that , i never buy anything online or authorize anyone to take my money. i asked her to call me back , she didn't call me it was Friday. following week i called in again spoke to a lady who sent me dispute form , i filled it, sign it and send it back to her and there was no feedback. i follow up this week again she forwarded my mail to dispute dep no feedback its Friday. its been 3 weeks now , no refund has been process , no communication , i am very disappointed with your service.
