Uninstalling this plugin

Hi, I am building an e-commerce for a client.

Stumbled upon this plugin and personally didn’t find it useful.
Tried to uninstall but I am stuck with this annoying

zaddon_data div that has display: block
I can’t override it with css to hide or find where it’s coming from.

Please help remove your plugin.
