I am giving this "company" a 1 star review because I question its validity. Backstory: I received an email from them last week. I have never heard of this "company" before so I called them to ask about it. No answer. I tried 4 or 5 more times to no avail. I think left a voicemai . No call back. I tried calling them a couple days later, no answer still. I left another voicemail. Still no call back. I tried again today, 4 more times today alone. No answe . I left another voicemail.
I am going to guess this review goes unresponded to as well. Just a hunch though.
