Telemarketer violating the DNC trying to sell siding or windows. I've never given my number to any company selling these things and so far in the last several months I've gotten at least 8 calls from different area codes which I have blocked. They call several times from the previous numbers that I block after the first call from said number. I guess they figure out that I blocked the previous number. They then call from a different area code and I tell them to stop calling me and then I block that number too.
