Messo — Did not receive the order

I placed the order on 4th march, 100 times make the complain, the order is at my place since 12th, these ridiculous people don't bother to deliver that product and customer is waiting since 10 days, now he cancelled the order with me? Now I'm not able to cancel the order as they show it is shipped, what the hell I have to do? No idea, they are not ready to refund my money as it is prepaid.. Please help me. It's hard earned money. How these fake people will do like this.
