Please provide a list of these bugs you disclosed and the shady excuses you got. As far as I remember you were simply wrong with your assumptions, but maybe I have missed something.
The "Updraft" issue was first reported in April and has already been fixed. It should not occur in WP Toolkit version 6.3.0-7223 or newer. Which WP Toolkit version are you using? Updates for the WP Toolkit extension are rolled out gradually, so it is possible that your installation does not have it yet. Same principle as explained before regarding Wordpress updates.
