​@Emin you can't delete users in the Free plan, you need to be in the PRO plan to do that.

My suggestion: upgrade to PRO, then delete the users, and keep it under 500 subscribers to keep your bill at $15 per month.

Thanks for help!

but I am able to delete more than 4000 contacts.
I think it is bug, because I can see 2872 live chats but I can’t see them in contacts menu

what i can do without pro plan? I am quitting so can’t renew Subscription 

thank you for support
