Iphone charger melted and phone will not turn on?

Last night i put my iphone on the charger, when i woke up my charger was melted, i put another charger on it and that one melted too, now my phone will not cut on but shows the screen that says it needs to be charged.

If I were you I'd contact Apple and tell them that both your chargers melted and ask them if they can replace at least one of the chargers or replace the phone.
