I've received 4 voicemails from this number today. Pretty annoying and downright bold of these scammers to keep trying. If you dial the number from a land line, you'll get a message that the number is disconnected.
Called and said they were the IRS and filing a lawsuit. Called the number 346/971-6385. It rang and rang. When someone answered, they were speaking in a foreign language.
Received a total of 4 phone calls from this number yesterday, with two being left as voice mails, though it was only a partial recording with most of a phone number and a message to call back ASAP. After the last call, which I was available to answer, I tried to call back and Verizon said the call could not be completed as dialed. I figured it was a scam because if the IRS wanted what you have, they would just take it; seize your accounts, etc......
