BB Curve :: 9300 - Not Switching On?

Yesterday Morning I put my BB Curve 9300 on charge for around an hour to get its 100% battery back as I would be traveling for a while in the car with out any source to plug my BB in, My BB was perfectly fine. Throughout the day I used BBM quite a bit and some of the games that I had installed onto my BB. Around 3pm I notice my BB was very low on battery so I put it on charge and left it for 30 minutes and returning only to find out it had not charged at all and the battery was empty> I had checked to make sure my charger was firmly in the plug socket which it was and made sure the cable had not come loose from my BB which it had not. I took the battery out of my BB and gave it a good blow and the inside of the BB too as this normally works. I put my battery back in and a solid red light came on which then faded. Usually When you put the battery back in the phone starts up and it works fine but now the red solid light will not even show.

I have tried leaving it on charge over night and that has not worked helped at all

P.S. I have had my Blackberry Curve 9300 for just a week as it was a replacement given to me by my provider when my last Blackberry failed to work.
