Gonoise.com — not refunding the money

I ordered one gonoise x3 extra bass earbuds for me but then decided to choose another product. So when i cancelled they said as it had already been dispatched so they can't do anything but when the delivery comes i can deny the package and when the product would reach their workshop they would initiate refund and contact me. It's been eight (8) days and still they haven't contacted me or returned the money. I don't have any product and they are still not returning the money.
