I cancelled my TWC service and they call a couple times a week. Every week. And they only talked to me one time and they were very unprofessional. I think its id theft scam.
I am getting calls from this number as well. The location is el segundo CA. It has been pretty persistent and has even called twice in one evening before... and I have yet to receive a voicemail.
Everyone wondering who 310-765-1089 is and why they are calling you; you have Time Warner Cable don't you? Time Warner is calling you to offer you promotional goods and services IE soliciting.
I believe you can call TWC and have them remove your number from your file under your contact information, but then they wouldn't be able to contact you for any other reason.
