Well, your in a "catch 22" situation here. If you call TC and they tell you to send it back to them, when they get it they will replace all the internal parts with factory "stuff" and there goes your trigger job you just paid for. Unless you first remove the sear and other "stuff" that the trigger work was done on.
If Mike (censored word) did the work, call him up and ask for a lighter hammer spring. Those are not difficult to install.
BTW, I agree with Keith....hammer extensions are not worth the trouble they cause.
