I got a call from this number some girl giggling and a guy telling her what to say in the background and when asked to leave a message for who they were calling for they hung up.
Caller stated he was from Micro Solutions doing a survey on air quality. However, not much info was provided and some questions seemed to be fishing for info that would tell them when I am home and whether I have a dog - serious alarm bells going off at that point. When I started to ask him questions, he quickly stated I would be contacted if a win a drawing and hung up. Note that similar calls have been reported on other 253 area code numbers.
