LG KC910 Nothing but problems - Will not work

I received my LG KC910 3 weeks ago and over this period of time it has worked for about 4 days. The phone freezes and shuts itself off. Latterly it would look like it was on but nothing would appear on the screen other than a very faint background light then it would fade out. The battery is fully charged and I haven’t had it on or used it enough to use up any of the handset memory. I am very disappointed in the company I bought it from as they are ignoring my messages that I have issues. They did not take so long to take the money from my account. Shame really as sound quality, picture clarity and ease of use was great..if only it would work. Waste of money.
I expect in this day and age any mobile phone to work but this phone will not even perform the basic functions.
