Charging Problem

Hi i got lumia 620 for like 6 months everything goes okay but suddenly today when i was trying to unlock my phone nothing happend , yesterday i had like 30% battery so i thought that i would need to charge it while i putted the cable nothing happend still black . Also removed and putted again the battery and still same thing. Tried to hard/soft reset and the phone doesnt vibrates
What should i do ?

How long was it plugged in? Sometimes it may take a while for a phone to wake back up. (make sure its plugged into a working outlet with a working charger)
