how to rephrase "transfer/direct a phone call to xyz department?

I'd be more likely to simply say Sales, please.

I was about to say exactly the same myself.

In the US the question is rather academic. First you encounter a recording:

"For English press '1'; por espanol marque numero dos". Then you are directed to a menu. If you're lucky you may get to speak to a real live person who may be in India. At that point I might say: "Could I have customer service, please?"

I have no evidence that Americans use verb phrases more than anyone else.

Exactly, But after you encounter the recording, they tell you to press zero if you want to talk to an operator. The operator may be in some foreign country's call center. But the call center in my country train their CSRs (Customer Service Representatives), they give them accent training and having undergone the essential training when they speak , they speak fluently and sound like native speakers, even the person (the native speaker) receiving their call gets the impression that he/she is talking to somebody from his own country. So they are very well-trained and have good grasp of the language they communicate in.

Management, and the representatives themselves, may live under the happy illusion that they sound like native speakers. It's not possible for more than a tiny minority of non-native speakers to sound convincingly like a native, and the call centers don't fool anyone.
