Can anyone let me know if they have had any dealings with California Sports Investments, or know anything abuout them? (http://www.californiasportsinv.com)

I bought a basketball jersey from their website, to be shipped to the UK, paid with Paypal, but never received an acknowledgement from them. I emailed them some time later but haven't had a reply. I have tried calling but no answer. The jersey is still shown for sale on their site.

Any advice would be appreciated.
