I wouldn't panic ,it's early days yet ...Essencia seem to be re-building their website and may not be able to contact you.
PayPal will tell you to wait so many days, before entering into a dispute....give it a bit longer.
Keep your e-mails regarding these transactions, as it will be easier to deal with if you file a dispute.
Having had one or two myself , I have found PayPal to be pretty enthusiastic when it comes to getting your money back...!
If my wife catches me checking up Essencia's web-site I'm going to have a pretty good excuse...can you help me with that...!
