Loyalist Exam Services

Beware of possible additional fees for a flaw in their exam scheduling system...I really liked this service the first time I tested with them, two days ago. The second time I tried to get a test scheduled is when the problem occurred. I got a new voucher from my school. I entered the information into the testing company's scheduling window. I used my new voucher number. I chose a new test date. I received an email confirmation with my date and time which was scheduled for the following day. The next day, the day I was supposed to test, I get an email saying they canceled my test because their system allowed me to schedule under my previously taken exam. So they have a flaw in their scheduling system AND they want to charge me $5 extra for canceling my exam within 24 hours when they canceled my exam. Betty in customer service is not willing to override the $5 charge because they have a flaw in their system. Also, I can get everyone BUT Betty on the phone or anyone else in Betty's department. I have left two messages on that extension and have not had a call back. So frustrating.
