Spam Calls on TelCel

For the past month+ I've been getting multiple spam calls a day on TelCel.  My phone warns me of "Suspected Spam" so I never answer them, but it's annoying nonetheless as I keep my phone/charger in the kitchen when at home and found myself running from other rooms to check to see if it was a legit call.  

Someone on Facebook posted the same issue and another user gave this link to Profeco's registry to avoid telemarketers, etc.  I registered my TelCel number 4 days ago and have not a Suspected Spam call since!

Here's the link.  In the first field marked LADA, enter the first 2 digits of your phone number.  Continue the rest of your phone number in the next field.  You  likely won't have anything in the Extension field.  I checked all the boxes under Sectores.

Click on the call then immediately disconnect it. Go to your recent calls icon and when the recent call comes up
It should have ! Mark on it. It will show the number. Scroll down to block this caller and click it. . That # will be blocked
