Legal rightsI've read up on the relevant Swedish Law as much as possible using google/bing translate.
1. Swedish
distance selling regulationsDefinitions:
'consumer' means any natural person who is acting primarily for purposes which are outside business activities,
"trader" means any natural or legal person who is acting for purposes relating to their economic activities.
4§ says that contract terms that are to the disadvantage of the consumer are void. This may apply to KnC's "business purposes" clause.
10§ gives you a right to cancel within 14 days of receiving the order.
2. Swedish
consumer actGives you a right to get a refund before the order has been delivered/shipped.
3. Swedish
Sale of Goods Act (contract law)
Lots of interesting clauses here as well.
This law is appended if you buy as a person and not as a company. That's why KnC says that you are a company.
Everything you buy trough internet, over the phone or if a door knocker comes give you the law about 'distance buy'. Worth to mention is that this law does not apply if you buy anything that is custom made.
And YOU need to pay for the shipping back to the company you bought the product from. And as you said, this within 2 weeks after you received it!
