Did you mention things in your tip that indicate illegal presence?
Way to get your tip ignored:
>muh naybers are messican
Way to get your tip acted on:
>There are 20 occupants to this house which only has 3 bedrooms. [which is common for illegal aliens] Judging buy their work attire (reflective vests and hard hats) look like they work in construction [which is a common profession for illegal aliens] and they leave at X time, filling all seats of their cars which are very old and in apparent disrepair [which is common among illegal aliens] (license plate numbers) [so that they can look up to see if the DMV database information cross matches with any DHS information]. They speak no English and I heard them speaking Spanish [which is common for illegal aliens]. They moved in less than two years ago [which clues the agents in that if these are illegal aliens, they might be eligible for "expedited removal"].
Find out such information, tell the truth, and keep submitting new information/tips.
I see that you live in the Lower RGV. The US Border Patrol is often more responsive (I have been told), so write down all pertinent information and then call the local Border Patrol station and ask to speak to a supervisor. Be sure to tell them you submitted tips before because they might need to coordinate. Since you are so close to the border, look for signs of that house being used in alien smuggling and take notes.
