I had to cancell my journey

Nedbank debited their loan twice in my account 27th and the 8th April. So I had to call their call centre where I was told that its systems error and their urgent time is 3 to 4 days. Imagine the money that was in my account I had to go to Cape Town so I had to cancell my bookings because of such in convince and I left a message for the manager to call me coz I wanted to talk to the manager and they were in a meeting. Till today I'm still waiting for their managers call. This happened on tuesday and today is thurday no one came back to me.
