Who to contact with proof of postage when saying equipment hasn’t been received

[CharlieJ1]

I cannot find anywhere who I need to contact to show proof of postage. Had email today saying I was going to be charged for not sending any box back. 
but I haven't sent it

Is that a typo and you meant to type but I have sent it?

[GD1]

@CharlieJ1  Have you sent it?  the last line of your post says you haven't?

If you have when did you send it?

[CharlieJ1]

Apologies. I'm tired. The sky box has been returned.

@CharlieJ1 
I’ll escalate your first post to Sky when it’s ten minutes old and the Messaging Team should contact you to,orrow. 

You need to watch out for a post from one of the team inviting you to a private chat and then you should see a blue/red speech bubble at the bottom of your forum page. You’ll have 48 hours to click on it and start the private chat or it will close automatically. If you fail to respond to a chat reply within 48 hours the chat will again close down automatically even if your issue hasn’t been resolved. Replies from Sky aren’t instant so you’ll need to check the chat thread fairly regularly.

This link explains what happens.
