I order an item from online shop.The site of the shop is www.jarvisonline.eu.When i received it i saw that i can't use it because the description giving me from the shop wasn't full.I get in touch whit them and they told me that i can return it and i will get refund of my money.I send it back to them and now they are not answering to my e-mails and phone calls.They are not giving me back the money and they don't give me any explanation why and it's already 3 weeks since i send it back.What can i do now?
