Unfortunately there's not a whole lot that can be done if the # comes up as restricted or blocked. VZW may still have a policy where you can request them to research the # and if there's a pattern of abuse; 5 or more calls from same # within 48-72 hours, then it can be blocked but only for up to 60days. You'd have to call and ask though.
Otherwise I think changing the mobile number would be your best option, there's no fee to do it if it's a harrassing situation.
A possible option is to block incoming calls to numbers in your contact list. Many phones offer this option under the security settings on the phone itself.
Settings & Tools menu > Phone Settings > Security
Your security code is probably the last four (4) numbers of the phone number.
Unfortunately, VZW does not offer an option to block unavailable or restricted numbers from contacting your phone. As previously mentioned, some phones have the option of restricting calls to your phone to those only in your contact list, that way only the numbers in your contact list can reach you.
Also, VZW has the ability to change your phone number. There is a $15 fee associated with it, and it will prorate your usage for the month, but if you call Customer Service, any VZW representative will be more than happy to assist with providing specific details on what that means for you. If you do decide to change your number, call customer service from a separate line, with your phone available.
If you're a Verizon VIP member, they should waive the fee for you. They may also do it as a courtesy.
I think you may be better off letting whoever is calling know that what they are doing is illegal. Ask to speak with their manager, let them know that you'll be filing a complaint with the FCC. There are other options to stop this outside of what Verizon can do.
It is legal for a company to solicit a line only if the caller is not an automated message or recording, and as long as the person receiving the call is NOT on the national do not call list.
It is advised you add your # to the national do not call list (
Thank you, everyone, for the responses. While I did get the answer I was looking for(though definitely not the one I wanted), I feel some things need clarified.
These are not telemarketers. They are bill collectors looking for a certain person. They do NOT have the right to continue calling me at all hours/at work after I have asked them to stop even if they were telemarketers. I wish they were sales calls, because then my rights would be much broader. I could ask them for a company name and expect to get it. Adding this number to the do not call listing will help keep me from getting unwanted sales calls in the future, but it is going to do nothing to stop the people from the collection agencies from calling looking for the previous owner of the phone number. The only thing that will do that would be to force their hand in revealing a phone number by blocking all attempts at getting through on a restricted line. Apparently Verizon is more concerned about the privacy of anyone and everyone but their customers. This is a feature that needs adding to Verizon.
So again, thanks to those that answered. Maybe someday Verizon will get with it and realize that the needs of their customers who are paying them should come before the needs of shady debt collectors who refuse to understand that the woman they are after is no longer at this number.
