Answer: It’s a must to have an emergency contact on your phone for any emergencies that may arise from an unknown number, but if you want to block the contact from calling you again there are a few easy ways to do so.

You can always change their name and just reply “No” when they call, but the way I usually do it is going into my Contacts list, selecting all of their calls and texts, then push Delete Contact on them. I find this more efficient since all their past memories disappear as well.

If will be done automatically for an iPhone with a limited time span by activating a particular settings option called “Do not disturb.” Turning this setting on will send those who phone you voice mail without hearing from you.

For android users, go to the contacts list of blocked numbers, choose all numbers added to it and send them delete or remove from blocked numbers. By doing this you are blocking the person from calling you ever again on any number for a limited time span.
