How to completely delete Bitnami WAMP server?

Question

I installed Bitnami WAMP and I tried to uninstall it and use AMPPS instead of Bitnami WAMP.
I deleted Bitnami WAMP but it wasn't deleted completely.
I can still find WMAP files in 'Setting > Service' : 'wampstack Apache' and 'wampstack MySQL' files are still there.
And, When I run AMPPS, I can't run Apache and PHP 7.1.
An error message occurs and it says "Apache port:80 is being used by another application"

fyi, This is how I uninstall Bitnami WAMP :
1. Run Bitnami uninstall file
2. Remove Bitnami folder
- Even after running that file, Bitnami folder still remained, so I remove that folder by GitBash.
- rm -r -f Bitnami

How Can I remove Bitnami WAMP perfectly?
I searched google a lot but couldn't find how to do. ;(
I need your help.

You can find the PID of the Apache and Mysql processes using netstat:

sudo netstat -nlp | grep apache

and

sudo netstat -nlp | grep mysql

And then stop them:

sudo kill -9 PID

After stopping the processes it should be possible to remove the folder.
