Another "survey" scam/spam call. When you call the number, you get a recording that says, "Thank you for calling. The survey you are calling about has ended." They don't provide any information about who they are or what the survey is about. I called the number right after I got the call from them, so how could the survey have ended?
Other numbers with the same recording when you call them are 415-529-4227, 415-523-6755, and 415-906-2127. I've blocked them all.
