Discounts Cube Basically they scammed me. New York New York

I placed an order for a computer monitor. After two days, I used their online chat service to inquire about my order. They told me that there was a problem with my payment. They asked me to send them money over PayPal which will be 10 dollars less than what I would pay with a credit card. They also told me to send them money as an option on PayPal sending money to a friend. I did that. After about a week, I tried to contact them again to check if my order was shipped. They did not respond to my emails. I tried to use their online chat service. As soon as I gave them my order number, the online chat disappeared. I emailed them several times, but I have not gotten any reply or any respond.
