Caller left some garbled message, words were too slurred to understand, sounded drunk. I tried several times to call back and no answer. I looked up the number on Google and found the name "Corner Solid Solutions". The web site button went to a Virus Total user "DALEJAKECORNER", but it says the user is Banned. Web search results show that person is a fraudster who falsifies information.
Must be some kind of computer scam.
