Since contacting facebook also didn't help I would suggest you to create a new account. But it will involve a lot of hard work making friends again, photos will have to be uploaded once more, tagging and what not!
This part is not actually an answer regarding facebook, but it is an answer by the community who got fed up of facebook's privacy related issues and have come up with innovative project DIASPORA.
DISCLAIMER: I am not associated with this project as a developer. I just wanted you to know about an option available. I have accounts in facebook as well as joindiaspora. So don't regard this as advertising.
If you are interested you may consider DIASPORA ALPHA, which is available through https://joindiaspora.com (invite only) or the Diasporg which is a community supported Diaspora pod where you can open your seed (account).
Speaking about the advantages, there are many:
- Share what you want, with whom you want.
- Diaspora lets you sort your connections into groups called
aspects. Unique to Diaspora, aspects
ensure that your photos, stories and
jokes are shared only with the people
you intend.
- You own your pictures, and you shouldn’t have to give that up just to
share them. You maintain ownership of
everything you share on Diaspora,
giving you full control over how it's
distributed.
- Diaspora makes sharing clean and easy – and this goes for privacy too.
Inherently private, Diaspora doesn’t
make you wade through pages of
settings and options just to keep your
profile secure.
