202-777-1100 Washington, DC Continuously call me after asking them to stop, demanding my name taken off their list. Washington DC Washington DC

 Weeks ago I received many calls from 2027771100. I answer the phone hangs up I call back number is not able to receive calls, this goes on for days, at least 5 times per day. I was able to speak to someone a female with a foreign accent telling me I've been granted money from the U.S. Federal government. I play along knowing this is a scam, not giving any additional information about myself, they knew my name and address, phone number. Towards the end of her speech, I tell the accented woman , I know this is a scam, take my name off of your list, do not ever call me again. She gets angry and asks why did I wasted her time I start to laugh. At this point she tries to recover and tells me I'm on a list I will receive, I think 5,000.00 dollars, she tells me to write down a reference number and call a 1-800 number. I repeat take my name off of your list don't call my number again. I hang up the phone The next day the calls start again. I answered the phone this time an American lady answered assuring me she would take me off the list, no more phone calls. This lasted a couple of weeks. I am back to receiving 5 plus calls per day, same scenario. I'm so frustrated, don't know what to do.
