@Parvinmoussavi Removing your autopay/payment card would not suspend the account immediately unless your payment was due today. If you want to suspend the account (pause it) immediately, then you need to log into your account and select Plans/Add-ons tab, Lost/Stolen and then Suspend service. You will, of course, then need to go back and Resume service if you needed to reactivate the account again.
You should also change your email and password if the account/phone is hacked. The email can only be changed with the assistance of customer support via chatbot. Here's a link to chatbot: https://www.publicmobile.ca/en/on/get-help
edit: @Parvinmoussavi You should also remove your name from your post by clicking the downward arrow top right on your post and then edit/delete. You are posting on a public forum so it's never a good idea to share personal information.
