## Why this rule exists

The confirmation arrives from a number the consumer has never seen before, so it is exactly the moment they may want to check who is texting them. Giving the HELP route here closes that loop before it becomes a complaint.

## How to fix it

Add "Reply HELP for help" or a direct support contact to the confirmation.

## Example of a compliant value
