Contact Title Co. and nicely suggest that if you're not paid, well, gee, you'll need to contact the lender. TC won't pay you but will get on SS butt to do so. Works 98% of the time. Also, with any co. CHECK THEIR REPUTATION before you do the job.
When it turns out to be bad, just give it back promptly. Whatever fee you got goes down when you have to add 'collection time/effort' to it.
