call to tell me i qualify for government grant in the amount of 7000

these people called me several times rather persistent for me to receive a code MJ505 code to be called to another phone number 206-333-3629  saying that I can pick this money up at a cash location so when I called the number the guy got really upset because I blocked my number so  I called back they didn't answer so I blocked them on my phone. Can you please let me know the out come of this situation
Thank you
