Only thing I can see you can try is to use a sink plunger or drain rod with the rubber plunger disc [tape the joint so you don't loose that also] plunge the pan bend it may cause enough pressure to pussh it into the 4" stack pipe [sewere pipe] then on into the manhole where you must remove it. Failing that toilet removeal if you are able, which would be cheaper than calling in drain clearers.
