Horrible Service from Nedbank

I called Nedbank today trying to get hold of them to cancel a credit protection insurance, but they sent me from pillar to post. I was transferred to more than 5 people with no assistance and the final person(from AIG) to pick up was very rude and requested a reference number on the statement which was not on the the statement and he could not help either without it. He referred me back to nedbank and the phone rang forever with no answer, I ended up spending more than half an hour on the phone with no help. So disappointed with the nedbank.
