Extending TIP after receiving Temporary Resident VISA

I spent about 3 months trying to do this with no success, I resigned myself to just have a copy of the law section stating that the TIP is good with the length of temporal residente. The only thing I have not tried is physically going to Mexico City office. Not going there due to pandemic...I did DHL a request with all paperwork to Mexico City, but never got a response.

We have never been asked for TIP verification for the 6 months we have been here and during our trip down here.
