Got this on 10-1-13 the number was-301-548-4532 was ask by the caller if i was diabetic, and also ask about any cancer treatments or relatives had cancer it was real fishy after I told him there was no cancer in the family he hung up.
Area code 301 is southeast of Washington, DC in Maryland. I received a call from this number at 7:50 am. The caller did not speak and hung up immediately. It's odd as I once lived in that area code. Very odd. I called the number back half an hour later out of curiosity (My cell phone number is blocked) and received: (tone for baby bell message) "The number you've dialed is not in service." What I've read about these calls is that they're all scams using some computer to hide whatever number they're actually calling from cloaking it with numbers that are "out of service". Darned people anyhow ...
