Called my cell and did not leave message. When I called back from my work phone a voice recording picked up and said "Thank you for calling. The number you have dialed is not a working number. Please check the number and try again. Thank you." It just repeats over and over. So sick of robocalls! Needless to say, immediately blocked.

This caller calls me several times per day. The one time I answered, a foreign sounding man explained that he is with my cable provider, Spectrum (formerly Time Warner Cable). It was an aggressive sales call, and I ended up having to quickly and as politely as possible hang up on the guy after explaining that I had zero interest in changing my service. The number continues to call me once, twice, three times or more per day.

calls me multiple times a day leaves no voicemail ! so weird ive never tried answering or calling back too worried about it being a scammer

It seems to be legit from Spectrum. I only have internet and they're calling to try and sign me up for some new streaming-only package.
