How to Uninstall Kingroot

I cant uninstall kingroot. I done all the usual things I even did a factory reset of the whole phone wiped off everything and started from scratch. I even tried several system root uninstallers from playstore but still same problem.

My phone is a Huwawei G535-LL (EE Kestrel) but still same android system. I dont know what else to do now, any ideas would be appreciated
