Well since I’ve been mostly in customer service jobs I’d like for people to know that the reps don’t make the rules or decisions. When there is something about a store or service that’s undesirable such as prices then it’s something to bring up to upper management or just let them lose you as a customer. But you can be as nice to the reps as they are to you.
If you can frame every guess so that it can only ever have a binary A/B answer, troubleshooting and guessing are pretty much identical.
