Removing 'Any Desk' App from Mac mini

I went to what I thought was NETGEAR support site and somehow I got connected to N Solutions as I was struggling with access to My router and the set up of a new Access Point. The person jump on my issue and used "Any DesK" APP to control my Mini , Router and AP. Then worked set up a service agreement to cover the cost of the work and all service for three years. I stopped all payments the following AM and then changed all passwords. But I can"t remove APP "any Desk from my hard drive and I can not find the installer package
