No Response From Supplement Shack

Has anyone dealt with this company before?

I placed a c/card order of around $70, 5 days ago. Silly me, as if using my card on an unknown website wasn’t bad enough, I forgot to keep a copy of my order details. One was supposed to be sent to my email, but nothing came. I contacted them via email (form on site would not submit) the very next day and once again, no reply. They have an international phone no. which I’m going to have to try. All in all ,their set-up seems quite unprofessional.
