Clogged Extruder

Awhile ago i was running a print on my Robo and at some point during the print the extruder became clogged. I watched the video on how to clear the clog from the extruder but once i took the screws out and looked it was much worse than what the video shows... the extruder is filled with filament all the way to the top. I have tried heating the nozzle and seeing if I can clear it but have had no luck. i have attached a picture of what it looks like, I hope someone has an idea as to how to clear the clog if not looks like ill be ordering the E3D hot end... lol

 

My printer came with ABS fillament i ordered. Its not getting melted. Gets stuck in the extruder.
Temp set to 270 still not coming out. It does, but very very slowly and very hard solid string.

Not sure whats wrong.
Dont want to switch to PLA
