This is what I just did. First I went online into my cell phone account with Verizon and blocked the number for 90 days. Then I called 718-559-4080 and held until I got to speak to a reprentative of Optimum directly. I explained calmly that I had recieved 22 phone calls from this number within the past week and that I no longer even live in the Optimum service area. She transfered me to the Optimum "do not call" line where I then input my phone number. The Optimum "do not call" list may not go into effect until 30 days after you imput your number, but between this and the temporary block through Verizon it should work immediately. The whole process took about half an hour.
thanks to this info - ive been getting missed calls from these people so frequently. months ago i do remember cablevision calling me and i forgot not to pick up again.
I do not answer and they do not leave a message. Anyone who calls me unsolicited goes to the answering machine. If they do not leave a message they have zero chance of ever talking to me. If they do leave a message they may hear from me if it is something I want to talk to them about.
Got another of these calls again tonight. Have told them many times in the recent past I am not interested in additional services. Now that i know it is Cablevision again i will continue to ignore the number. thanks for the heads-up on who this pest is again.
