When you do a purchase the purchase is made in a "valuated" manner. When you pay with BTC you pay a price what it costs translated to US dollars.
That value is determined in that particular moment when you purchase the item.

If the price for the merchandise is $1000 then you perhaps pay 5 BTC for it at that particular moment.  If times go by and things doesn't pan out as it should then you want a refund due to some circumstances then they agree to pay you back you will only get back that much BTC that it's Worth by the time they actually DO the refund..

For instance if BTC failed and was not Worth more than perhaps $50/BTC then you would get 20 BTC back to you, if it's Worth $500/BTC then you get 2 BTC back... Then again you could hope that the BTC wasn't worth much then you'd get many many bitcoins but again who wants them at that time?!

It's that simple! Why??

Because today companies cannot purchase services and stuff for BTC, they simply need to Exchange it down to a currency that exists and that is viable for use between each and everyone.. $ SEK, Euro , Yen etc etc..
If the World was a wonderful Place then we would not have any other currency BUT the BTC only then when the value of it doesn't vary that much you would get as much BTC back as you payed but only then... We are about 20 - 30 years away if BTC still is viable..

This is an experiment that has been very sucessfull and survived two major crashes already and rebounced. That is the sign of self preservation currency and we can only hope that its here to last. It would be so easy for the World to use it.

Hope you now understand why things pan out as it is for the moment. For me KnC has been helpful with my RMAs etc and i'm running as it should. And i'm sorry that it hasn't panned out good for you.. Swedes have closed offices in Saturdays and Sundays and if you wrote something to them four Days ago you would probably recieve an answer in maximum six more hours until their office is closed for tonight.

Take care!
