Hi, after reading all the above comments, this one is going to seem tame. They called a few days ago, waking me up (but I was sleeping in,:) ) . I said Hello in my groggy sleep voice. They said, "Is this a business?" I said, "Sometimes." I run a home business with this number. They hung up. Usually the unknown callers on this phone are trying to sell some sort of business-to-business "service".
They called again today and I ignored it. When I checked the voicemail, there was thirty seconds of absolute silence. IDK?
Perhaps we should all call back constantly and block up their phone system.
