Unprofessional.
I'm giving Amcrest one star for the lack of professional etiquette that was not provided. The woman on the customer service line, during my phone conversation, told me "Yeah. Yeah." and proceeded to hang up the phone. I just called to verify information one my NVR purchase. Totally unexpected and unwarranted. So, the moral of the story: If you called Amcrest customer service line and you get a woman [her name eludes me at the moment], then just hope that she is in a good mood.
