Oh god... This reminds me of that time:

"A substitution has been made to your order: (A) instead of (B). Reply with Y to approve. "

<"Y"

"Because they were out of (B) sir"

I cringed so fucking hard

Try "Y or N STOP"

please call the number on back of your card

I feel like if this was vibe coded it would have correct English. "Please call the number on the back of your card"

Maybe they mean Y STOP or N STOP
