You need to report this call to the FTC (Federal Trade Commission) - they are impersonating a government agency. https://www.ftccomplaintassistant.gov/#&panel1-1
Just received a call claiming I am selected for a US Grant. Received several call a week ago saying same,. Asked me to buy a $100.00 iTunes gift card from Wallgreen and give him the number.
I continually get calls from this number. I do not answer calls from numbers i do not know. They leave a voicemail but cannot understand what they say. How do you get these calls stopped?
