Feeding in untrusted input from a support desk and then actioning it, in a fully automated way, is a recipe for business-killing disaster. It's the tech equivalent of the 'CEO' asking you to buy apple gift cards for them except this time you can get it to do things that first line support wouldn't be able to make sense of.
