MTN Quality Survey after 3am call

[mister]

Hey all

Anybody ever received one of these messages?

MTN is conducting a quality survey on the call you received from X

Was the call:

1. International
2. From SA
3. SA Call Centre
4. Prefer not to say.

It was my own landline forwarding a call to my mobile from my security company. I'm curious about what MTN is doing... Are they going to start policing robocallers? (Wishful thinking...)

Been getting these as well.
MTN already knows where the call came from based on CLI.
How do I stop this MTN data gathering
