Baytech Web Design Terrible experience San Jose, California

I had a extreme terrible experience working with this company. Most of the terrible things happened to me are like the other reviews.

I have Baytech to design a online printing web site for me around 2007 and 2008. Right after they finish the web site, the economy crashed and we dropped the project. We didn't test the web site thoroughly because we thought we were no longer need the web site and I signed off the paper work to except the completion of the web site.

Last year 2011, we feel the market start to have potential for printing again. We went back to try to use the web site again. We found tons of problems and the web site was a trash.

The major problem - No way we could input our product size and weight for shipping!! There also tons of problems.

Another problem that they've never fixed for me is a server error. Everytime when we log in to the backend administrator page, it gave us an "server error
See below):
Server Error in '/site' Application.

After I spent thousand of dollars to let them fix the problem, they came back to me and said they need more money to fix this problem.  

Another issue is we paid $1600 back in 2008 to add a real time shipping module for UPS and Fedex. After 3 years of time I understand the web site need to have a update in order to work with UPS and Fedex system. This time they want to charge me $9600 to update. I'm not a technical person and if anyone have knowledge about this, please help me to judge it.
