Hostgator.com Domain Registry WhoIsPrivacy cancelled, did not refund

I had registered a domain name with Hostgator on 10/12/2022  (they have their own Registry) and signed for Web Hosting services with them and started to be spammed with phone calls immediately, so I called the Hostgator and they suggested their WhoisPrivacy service. I asked the representative specifically if I could cancel it as well and be refunded if the calls continued. He assured me that they would cancel everything I want cancelled, so I signed for the WhoIsPrivacy service that they offered. As the calls continued, I cancelled the domain name and Web Hosting service and everything associated with it on 10/17/2022. They did not refund me for this WhoIsPrivacy service, although I asked for a refund. They continue to charge me for a who is privacy service for a domain that does not exist anymore and they claim that it is their policy. In other words, Hostgator charges unfairly for a service that is cancelled and is not needed. I wanted to let everybody know of their unfair charge policy, which is basically a charge for a non-existent service.
