NedBank refund me and improve their services to client.

Today around 12:16 pm I tried to withdraw money using Capitec ATM but the Bank didn't have the money I wanted, so I went to ABSA ATM trying to withdraw again nothing happened then I tried to pressed cancel so that I would get my card bank nothing happened so I decided to call NedBank agent to block my card but they took long to respond due to poor service after 2 minutes while waiting for a respond from NedBank agent I received an SMS reporting that my money have been withdrawn from my account ,after that a nedbank agent pick up and block my card but it was useless anyway the money was gone and open the ***** case but they told me they can't confirm if I will be refunded and they said they will respond me after 4 to 5 weeks ,am not sure if they really I understand that I need this money right now.Am so so disappointed right now at NedBank as it is been known as one of the biggest bank in South Africa, their service is very poor .I wish I never used their service.I will make sure I take this matter serious because I know they will come with excuses e.g why didn't I used nedbank ATM while they know very well that they don't have NedBank ATM everywhere like those big banks fnb ,absa,etc.
