Cresta Poor customer service

Without warning all my wifes cards were blocked. When she went to the branch they informed her she needed to be RICA compliant again. They would not accept any proof of address she brought but had to go home twice to get documents they were satisfied with. All vert well however my wife and I had sat in the same chair in Cresta branch leass than three years ago doing all the RICA issues. My one had been updated but my wife who did it with me at the time was not. The bank worker was rude, intolarant and generally not helpful. Including the supervisor when called to assist. I will never recommend anyone to make use of this bank but then all banks seem to be the same with not one single bank standing out with its customer assistance.
