Placed order and paid - but no response and no way to get hold of them.

I have placed an order # *** and paid online and sent proof payment, no response; their number is not functioning! I Dialed Phone Hotline:*** I press 2 or 2 and the call just ends. I can not get hold of them. I wish I had read the reviews of previous customers before I bought from these ****s! I am taking them further if I don’t get my full refund. !How can they still be allowed to be in business on the internet.
