Advanced Clinical Research Institute

I was called by the Anaheim Clinical Trials for a new drug study for a certain condition. However, after I went there and filled out all kind of paper work, then I was told that that study was for something else and I was there for the wrong reasons. It was a two hour drive from my place in Los Angeles traffic and it wasted my entire day. I have their emails to prove that they called me for my specific condition. But when I tried to confront them, they refused to admit their wrongdoing, or own the responsibility for their mistake. Not even a word of apology. Instead they tried to put the blame back on me. Totally unprofessional.
