I’ve worked adjacent to customer service people in a call center. Honestly, they might not have known. Call centers are frequently terrible about giving their reps news BEFORE customers start calling in about it. Plus, low level call center reps generally aren’t exactly star employees and may or may not pay attention when told things.
That is possible, though from my limited experience (2 call centers) companies won’t tell Customer Service reps to deny knowledge of something that is public knowledge. They will have some sort of carefully constructed public statement instead. And most reps don’t care enough to do anything besides repeat the statement, possibly verbatim.
