Once I contacted IONOS on live chat they put a ticket in and i got an email around half an hour later saying it was resolved, and when i checked it out all was good…
the message i got was “Thank you for contacting 1&1 IONOS. We would like to inform you that we have now manually disabled the “cosy-address-book” on your Managed WordPress websites and your Contact Form 7 should now be up and running.”
