Motor recovery from borewell in Hyderabad, Telangana- Expert help required

We have a borewell of 200 feet, 4.5 inch dia. Couple of years back one submersible motor got stuck at 180 feet while removing for repair. The bore mechanic was not able to remove it, so we bought another submersible motor and installed it above the existing motor at 180 feet. Now we want to re-drill it, but we can't as the motor exists. How to remove the stuck up submersible motor? Any expert help.

Thanks Mukund
