220.lv - Breaking the law

I ordered & paid by card for an electrical item. Changed my mind within 15 minutes & decided on a larger item. The operator said she would check if I could cancel & let me know. She did not get back to me. The next day in the afternoon she said it was too late to cancel as item was with delivery company. I said I would refuse to accept it & when it arrived 3 days later I did not take it from the courier & it was to be returned. I asked for my money back and was told only when they receive parcel back. This has nothing to do with me, it is their courier, he informed them I had refused it so pay me my money. 3 weeks later and 20 or more phone calls full of promises no money returned. They are breaking the law which is not new to them. I have contacted Consumer protection but it takes time & they know this. They operate like crooks, how are they allowed to still be in business?
