James,
Thank you for your letter and the emails you sent to us regarding your problem.
I'm very sorry to hear of your problem when placing an order in our web shop!
We've had a few cases lately where especially American credit cards wouldn't be charged successfully in our web shop, but when charging it in our backoffice it worked perfectly - according to our payment provider this is often due to restrictions for online transactions that some credit card companies have. This means, just like noldar12 said, that some American credit card companies are putting a flag on most transactions from overseas, including Austria.
Contacting your credit card company to announce that there will be a foreign online transaction should solve this issue. Afterwards you will most probably be able to order successfully in our web shop. Please log out and in again on our website for the new order, as this will make sure that you have a fresh order attempt. I'm not sure what the cause of the problem with PayPal is, as this usually helps in cases like this, we'll investigate here.
If the problem persists with paying via credit card, we can then offer you to process your order in our back office as a solution - please check your mailbox for instructions.
Lastly I'd like to add that we're in the process of getting a major overhaul for our website, I'm sure you'll like the new one better. :-)
Again, please excuse the inconvenience this issue has caused!
Best,
Stefan
