I got 2 calls on the 30th. No message left.
I 67'ed the # and nothing happened. Very strange that nothing would happen. I tried again and waited longer. Finally a recorded voice saying it was Optimum. What a poor excuse for a cable company. Nothing but problems and they can even identify themselves with Caller ID, regardless of the # they are calling from.
It was from Cablevision/Optimum. The message was that it was 'very important' that I call them back. I called them back within 5 minutes and was on hold for 15 minutes before a live representative picked up. They wanted to update their information and asked for my telephone number, e mail address, or any other way to contact me 'in case of emergency'. Needless to say I was annoyed and told them that in case of emergency, contact me with the phone number they had on file.
Got multiple calls from this number within the same hour, with multiple voicemails left, which was quite annoying.
It was from Optimum Online, and on the voicemail they left an 800-number to call back.
The 800-number took me to an automated system where I set up text-message alerts with the number they already had on file for me.
Not the smoothest way of doing this set-up, but the number is at least safe, if nothing else.
