Default Help! HTC One Dead and Not Charging!

Last night I updates my HTC One to 4.4.2 Telstra update from 4.3. It charged normally for a bit and then after a while it would not charge anymore!
After the battery died I plugged it in again and it would flash a red light and then turn solid with the charging animation show up. Then it would turn off again and repeat the process. After an hour it got to 3%.

Now it is completely dead! Plugged in to power socket or computer, it wont charge or be recognised! I would really appreciate your help!!!!!
