Ive had my Telecom R100 cell phone for around two months, and yesterday a problem occured. I had 3 bars off battery, then all of a sudden I had 1 and the phone kept turning off. So when I got home I charged it for half an hour. Then I took the charger out of my phone and my phone just turned off. I held the button for ages, I took battery and sim card out, but nothing happened. Then I put charger back in and it came on, and worked fine. But another 20 mins later I took out, and it just turned off again. Then I left the phone charging over night, when I woke up, i took the charger out, and it worked for about 20 secs (had half a bar) then the bar went red and the phone turned off again. What should I do???
 
PLEASE HELP ANYONE!!!!
