I too got several calls from this number. When I called back it said 'this number is disconnected and is no longer in service. After reading what you folks have said about this number, I hope they are disconnected. Sounds like a scam."
Got the same call on my cell phone in Texas. Part of a voice mail was recorded leaving an "877" number to call back regarding interest rates on credit cards, I guess? This was around 9:10am CST
