I want to add to the list of scammed buyers from a calcutronics transaction. I can't get any reply from usedcalculators (also known as calcutronics). Prior to the transaction, and prior to my payment OF COURSE, I had 2 to 3 emails per day. Since payment, I have sent 10 to 20 emails with no response...I wish I would have read these prior to my payment. Anyway, I am at least going to spend my lunch EVERY day finding sites that can alert everybody of this company. Here is some more information about this unethical company BEWARE!!!
