MTN NETWORK ERROR🚨🚨🚨

I run a couple of server and I use MTN for our local developments.
MTN's network is unable to work with DNS type – TXT. (Google)

We switched MTN Sims but still same situation. When we switched to Telecel it worked perfectly.
We made a couple of users test out if it was working at their end but still same situtation. So it's a general MTN problem

Here's the test command:
nslookup -type=TXT google.com 1.1.1.1

nslookup -type=TXT google.com 8.8.8.8

You can try it out on your PC if you're on the MTN network.

I tried contacting MTN Support, but its like they have no idea what i'm talking about.

Anybody who has direct contact to MTN Personnel, please do so?
