Problem with Hardware Versand Shop.

Hello

So here is the story. I've ordered a monitor from german online shop called Hardware Versand. The monitor was suppose to be Christmas gift. But after a short while I was notified that they don't have the monitor in stock. I've decided to cancel the order and have send many emails requesting to do so. No answer. So I called them, I told the man on the phone everything and he said order is cancelled and my money will be back. That was on 19th of January.
Now we have march the 12th and no money or the monitor. I have phoned them over 15 times, sent them bank letter that said no money were transferred to my account. But all they said is that money was send on 19th of January. At this point I really don't know what to do, I'm writing them email and messages all the time on facebook but it seems they don't do anything.
Question is, is there something I can do ? is there still chance of getting those money back.

(Sorry if its wrong section)
