Can you send someone a 1099 Miscellaneous Income form for a bad debt for the amount that is owed to you.?

You know 100% that you will not be able to collect the money.

Also, do you need to send a 1099-miscellaneous income form to an individual from whom you have purchased resale equipment or parts for more than $600.00?

If so, what do you do if you do not have the social security number of that person?
Update: What is the deadline for sending a Miscellaneous-C form?
Update 2: - I meant 1099-C!
