I reported KNC for both of these
Unfair terms here: http://www.konsumentverket.se/Vagled...avtalsvillkor/
For failing to inform their customers the products were non refundable before purchase

Dangerous products here: http://www.konsumentverket.se/Vagled...n/Farlig-vara/
400 watts a cube+ 1 PCI-e connector = FIRE. I uploaded a few pictures of burnt KNC connectors and cables

I'll be reporting KNC to ARN as well http://www.arn.se/ .
I've got A LOT of stuff against KNC to put together so it may take a couple of days, but the more people that do it the more they will take notice.

I would also report them here http://www.econsumer.gov/english/report/overview.shtm
I just found it and will do it tomorrow but I think the more agencies we can have looking into this "company" the better.

Don't forget to report them to the police http://polisen.se/Kontakta-oss/Polismyndigheter/Sodermanland/
and file an application for payment with the baliffs https://www.kronofogden.se/Ansokaombetalningsforelaggande.html

 I'll be doing that if my invoice isn't paid by its due day this week.
