Is SAS Core worth it?

Does the SAS Core account rep actually have the power to fix issues with your listings, etc? The main reason I would want it is to resolve issues with listings, since regular support is obviously worthless and lacks any reading comprehension capabilities.

Edit: Also, can they help with Amazon Merch on Demand listings as well? AMOD support is absolutely horrendous. If your listings get attacked by fraudulent takedowns, getting them reinstated is a massive headache, and then if you’re lucky enough to get them reinstated, you can have ongoing glitches that keep you from being able to change the price or description, etc.
