If you call Spectrum for any tech support, you’ll get a call from this number to complete an automated satisfaction survey. So, they’re not a true telemarketer, but an annoyance anyway and I bloody well blocked the number.

Time warner cable automated feedback callback.
Don't really know if they're spammer or not. Not being a phone number I recognized... I didn't answer. They left a message which simply said, "For Spanish press one"... then the call ended.
