Recently, I discovered my identity and personal info has been stolen. I have been getting numerous calls from my credit card companies and bank telling my someone is trying to access my accounts, open new accounts and more info on me. I was advised to obain a copy of my credit report and FICO score but when I tried to do that, It said I already received XXXX on XXXX/XXXX/2015. I did not. It was someone else. Now I canot get this report because someone else already got it. It said I need a report number to access this credit report. I do not have a report number. What should I do? 
Please Advise, Thank you.
