My phone exchange is 744 and I receive misdialed calls for 774, all other digits are the same. People are calling {edited for privacy}. Nomorobo is useless now. I don't want to block this number, I want to block the callers from calling me by mistake. Can this be done without blocking each person manually? {Edited for privacy} will not remove this number from the web even though it is no longer in service. I can call this bad number because it redirects to a new phone number.
