How to make a customer service rep position sound good on a resume?

I need some help putting down the type of tasks on my resume please :)

I work for Safelite part time…I am a customer service representative. I receive calls from people that need to follow up on their existing claims or file for a new claim on glass damage for their vehicle. I am a third party of Chubs National Glass Service and Nationwide.

Sadly, there’s nothing much to my job I guess. I mean, sometimes I have to try to find out an issue with their claim like getting them assigned to a shop…other than that I usually have to transfer them to complaints, verification, sales, etc. I’ve had my fair share of mean rude customers
