Absurdity

I moved more than a year ago to Detroit, and I still can't get my address changed for many of my business contacts. I tired again today. I went on line, and tried 10-15 times to log in, I called customer service twice, I tried the contact us button, and nothing worked. This has been an ongoing issue and my forwarding with the PO is about to expire. No one seems to have heard of real customer service any more. Mellon Investment's website SUCKS and so does their customer service, but they aren't alone.
