Ebucks shop not communicating with customer complaints

I have received a wireless headset from ebucks shop about 2 weeks before Christmas, the arrival time and everything was fine. Found the headset not working no matter what I did charged 4 days every way possible. Tried every button combination nothing switched it on. Try connecting to all my devices nothing happened to turn the device on. The manual also is very uninformative so really is hard to find the problem. I sent 4 messages to them 2 from their own contact messa board on their website and 2 emails to them. Still no reply to date, except a email saying the message has been sent to ebucks and they will contact me shortly. I'm still waiting and their was more than enough time for me to get a replacement before Christmas. Bad customer service.....
