Nedbanks not so hot ***** hotline

Received an sms saying I'd just spent 55476 Japanese yen, which is strange cos' I'm sitting in Johannesburg and had just used the card at Builders, so their algorithm seems to be flawed. Phone Nedbank tell them the tale and get transferred to '*****' after waiting over 15minutes I press 1 and leave my details - they'll phone me back. They didn't. Tried again, waited 30 minutes pressed 1; the mailbox is full then I got cut off. Tried again, still getting through to ***** is almost impossible. Tried again, they try to get through to their own ***** division and I get lost in the ether. Finally I try and the lady was very nice, understanding my complete and utter disbelief with Nedbank and how impossible it is to get through to *****. There is no direct route. The system doesn't work. I've been with Nedbank for 33 years and when I need them they're nowhere. Will try again tomorrow and see what happens. I did manage to block the card, eventually; so we'll see what frustrations tomorrow brings.
