They call numerous times a day from different exchanges of the same number. I never answer and they never leave a message. No company name is shown, plus I'm on the Do Not Call list; so they're breaking two FL laws right there. It's annoying!
Got a call from this on my phone for work. It hung up immediately as my official greeting's apparently too long for it. Called it back and it said the "Survey was now finished and to press 1 to be removed from the call list." in a very bad recording. Suspect this is indeed spam.
