No Delivery

Hi.

I live in Ireland and ordered some items from premiumhumidors.com. The website stated that they would ship the items within 24 hours and notify me via email with a tracking number when the items were sent. I ordered the items on the 26th April and have not received any correspondence from the seller. I have emailed and tried to contact the seller on numerous occasions but i have not received any response at all. My credit card has been chraged for these items and i am unsure what to do now as the seller is failing to respond and was wondering what is the best way of dealing with this problem?Thanks for your time, Kind Regards, Karl
