No delivery, no communication

Ordered stuff on 25-11-2015. Paid immediately. I was promptly called the next day to confirm I paid. After that I had little to no communication from them. Had to phone several times. Every time I was assured I'd get my order. In December I received the wrong order. They sent me a cheaper replacement of one of the items i actually ordered and the rest was missing in the order. Again excuses and more promises. End of January I was told that on a specific date in February I'd receive my order. That date has come and gone. Phoned again, was promised another date and nothing arrived. Now they are not answering their phone or email.
