By the 'handed to delivery partner' it looks like they might have subcontracted delivery out to a different delivery company for yours.
Here is the email address to send them a query about your parcel
parcelforce@parcelforce.co.uk , but to be honest if it says out for delivery then i would expect it to be delivered today. They deliver right up until 6.00 pm so plenty time. Although I do understand how nervous and frustrated you feel as thats how I've been for the past two days
