Bogus invoices sent by scam company from information submitted to PPH in a post

Yesterday I posted a job. Today I have emails from a company that have taken the information about my websites and the job listing details and created a false email for £520.00. This means third parties have access to information within the PPH system and my computer. 

I'm getting calls from people who are not PPH freelancers as well.

Plus where are the contact details to email or talk with someone in PPH. I can't find them so I have to put this entry in a post.

Very unhappy with this.
