I got one call a few years ago. A young lady said as 介绍新的服务项目 from my bank. Then, she said the bank lost my information and asked me tell them (she also said to confirm it's me). I got very surprised that "the bank lost my information" so I did not tell her anything -- this is right!
Yes! Remember do not release your personal information to a call that cannot make sure it is safe!
However, some call from your bank and 介绍新的服务项目, that's normal. Just ask them questions if you interested. But carefully with your personal information!
