facebook blocked me from sending messages and friend requests, how can I unblock?

[Daniella]

I have been blocked for 30 days from sending friend requests and private messages to people who aren't my friends. Can I unblock this?

"Some of your messages have been reported as spam. To avoid getting blocked, make sure your messages are in line with the Facebook Community Standards."

and

"We received feedback that you sent friend requests to people you don’t know, so you won’t be able to send friend requests for 30 days. Learn more.

If you think you’re seeing this by mistake, please let us know.

The block will be active for 22 days and 18 hours more."

I 'let them know' that I think it is a mistake but havent heard back anything. People are contacting me via private message for work related enquiries and I can not reply! It is extremely frustrating and I'd like to unblock it if anybody knows how??

MUCH APPRECIATED!!
