TransUnion Intermediate Holdings, Inc. Credit reporting department,

Improper use of my credit report Report shared with employer w/o consent New York

I called TransUnion at - to put a fraud alert on my social security number after it was released by my employer to the wrong employee. TransUnion had me provide all information into the phone and than provided me with the address of -. The recording told me to send my personal information, social security card, and another form of identification, such as my drivers license. However no other information was provided, therefore I have no idea what I am supposed to send requesting to place a fraud alert on my account, no form or anything. The recording only said send my social security card to this address. I am in a great amount of frustration over the whole process and just want to place a fraud alert on my account to - and TransUnion. How can I get this done?
