Got a call from 240-800-9544 in the afternoon on Dec. 7, 2016. No message was left. When I called the number today I could tell it was a telemarketing center and when I asked who they were, they hung up on me.
Got a call from this number on my cell this morning. Caller ID showed "Maryland". No message left. Did not call back. After reading comments above, glad I didn't. I don't know anyone in Maryland and I don't answer unknown/unidentified calls.
Got a call from 240-800-9544 from Bethesda MD on Feb 27 2017; it was an electronic voice saying I needed to call them immediately regarding my credit card however they didn't indicate what company or what the issue was so I hung up. I have received calls from my credit card company before and it is always a live person and they always specify their name, credit card carrier and the issue, not a vague urgent message about my credit card.
