This is a customer help customer forum where Ziggo moderators come by every few business days in every topic, so that can take some days.
You can contact Ziggo through the chat or in a different way on the contact page.
The chat box (to be used 24 hours a day / 365 days a year) is automatic placed in the middle of the screen or at the bottom right of the page below, only if someone is available, sometimes wait a while.
