This is a scam company selling pharmaceuticals. They are a phishing company, and use bogus phone numbers usually in your area code to make them seem like a local company. This company is run out of Jamaica and Barbados. Its best just to ignore their calls..
Get repeated calls from this number 2-3 times a day at times. Sometimes leaves a message about hang up if this is not ******, and it isn't, but they continue with message, but say not to listen if you are not *****, but they leave a message on the machine anyways. At other times, they just hang up when it goes to the answering machine.
Same thing happening to me. It is so frustrating. I get a couple of calls or more a day and they leave no message. I also called back and it was internet based.
