Hoi @Ayham AlKawi 
 

Please enter your customer number(s) and postal code and house number and telephone number in your forum profile, which is only visible to KPN and to you, so that you can be helped more quickly.

So don't post here but in the link that you can click.

Hello @Ayham AlKawi, welcome on the forum! 

I understand that's it's annoying if you receive information not meant for you. Did you try sending it back? When you receive the mail/post and send it back with a note ‘vertrokken’ we will process this and you shouldn't receive any new mail/post for that user. Please let me know if you tried this. If you tried this and you still receive mail/post for someone else, then please fill in your information on your profile. Please place under ‘persoonlijke informatie’ the name adressed on the mail/post. Can you reply in this topic after filling it in?
