Some more brainstorming:

===

"Support Void", "Voiding", "Customer Voiding"

Tossing all customer support requests (and sometimes customers themselves!) into the void.

Pros: Sounds snappy and dramatic. Has humorous resonance with voiding your bowels.

Cons: Meaning not immediately clear. Sounds active when the problem is really more passive.

===

"Customer Neglect", "Customer Disservice", "Customer Ghosting"

Opposite of "customer service."

Pros: Meaning is more obvious because of its relation to Customer Service.

Cons: Not quite as snappy.
