Disappointed in Capital One Bank

I have been a Capital One Bank customer for many years. Probably 20 years or more and recommended this bank to everybody we knew or met. It used to be a great bank. Very easy to deal with, honest, respectful customer service and etc. You name it, they had it in the best of form. However, it started change. they took a turn for the worse and now they reduced themselves to just money disappearing from my Checking account without any explanation. I called several times and there is still no explanation. There are NO people who can take a responsibility there. Everybody switching me from one person to the next but the money is gone and there is no answer. What surprises me is that Wall Street Journal still lists them as the best bank, even people rate then as the worst failure. I went to look at the reviews. One star from customers. To me that means that I can't trust any of these institutions. Apparently, lying and stealing is a norm for them. Also they used to value their customers, now they just short of telling you they don't need any customers. It's a pain to start changing all the direct payments and such but has to be done. Can't afford to have money disappearing from Checking Account.
