I'd call police, your Attorney General and depending on what was screamed, your local police. If they are dangerous, you need to do this. It's harassment, threats, etc.
I have received multiple calls from this number, never harassing, 3/4 calls had a "pleasant" automated message regarding student loan relief. I won't return the call based on the info I read from another writer with another phone number associated with this one as I am also bomarded with calls from the 305-230-4061 number (Homestead, FL)
2024594441 calls claiming I am involved in a lawsuit involving BancFirst (not my Bank); next Student debt collector and claimed they were coming to my job to arrest me. My reply where do I work and by the way I reported these calls. Intimidation, lying and backpedaling began. I then gave them the number to the State Attorney General and the FCC
They call several times a day on my cell, and hang up. I finally caught a call, they are doing some sort of Obama debit relief scam. I started to politely ask them not to call me again and the phone was slammed as soon as I started to ask.
