******** of money by green bank

On December 16 I went to a Nedbank ATM at Ridgeway and attempted to withdraw R200. All seemed well with the transaction until the atm had to give me the money. The money didn't come out and the machine said there was a technical glitch but I received a notification from Nedbank that a withdrawal of R200 had just been made. This is so irritating because I waited to hear from Nedbank that the money was returned to my account as the machine had a technical glitch but NOTHING!! I've just been ****** of R200 by this bank. I'm so sick of Nedbank and their glitches, I mean every other week its something new JUST PROBLEMS PROBLEM PROBLEMS!! I changed my pin because having been a victim of bank card ***** after my card was cloned in June, I just didn't want to take any chances with this unsafe bank!!
