Customer Reviews for Needham Bank
Shawn
February 14, 2022 |
I had a personal checking account and a business account. All went well until I sent a polite letter pointing out that it is improper, and not good practice, to make online passwords expire. Why should they, if they are perfectly good and uncompromised? Nor is it proper to prevent me from seeing the new password as I type it (twice). Did I mention that this was a polite letter? I was only trying to be helpful.
A week later, I got two certified letters cancelling both of my accounts.
