(718) 521-4974 - Called me 10 times in a row from that number and from (305) 356-9999. Claimed to be from IRS. A well known scam. Delays before they answer back, like a telemarketing desk. Then female with heavy Indian accent answers. I didnt want to sit through their scam, so I hung up. They called back from the two numbers above, repeatedly, 10 times per minute. I had to call our IT to block the number.
