someone created a fake account, used my name and committed defamation on facebook. Can i be sued?

[jords]

So this is the case:

Somebody created a fake facebook account using my name and posted very bad things (something that could destroy the reputation) about the company that i am working at. Can I be sued even if I tell them I didn't do it.? I don't even have a facebook account.

additional questions:

1.) when we look it up on facebook. the post was deleted and the fake account was gone. but my company said it was there and the damage is done. can i still be sued?

2.) I live in the Philippines and I have read defamation laws all over the internet but haven't seen anything related to my case. probably best be answered by a lawyer who lives in my country.

thank you in advance.
