I just received a call from this number. The person had a heavy accent and he asked me to verify if this was the residence of "Mr. Sandra ******" He could not pronounce my first or last name and he addressed me as Mr. I asked where he was calling from and he rambled something off. Again, he asked me if this was the residence and i then hung up. I did call the number back later in the evening but just got an automated service.
I also got a call from 301-745-7000. Looks like some spammer/cold calling company. Very suspicious. Do not pick up and report to your telephone provider.
Also keep in mind you can actually report this to FTA.. I see many people are talking about this number in forums online..
Just got call from this number by a woman with a heavy accent. She wanted me to verify a checking account number on a bank. I asked her what bank and when she told me I told her I didn't have an account with that bank and she hung up.
