I returned all my three sky boxes with remotes and wires and a signal booster.

I returned all my three sky boxes with remotes and wires And also the signal booster because I cancelled my account with Sky. I recieved an email from sky that they recieved the equipment. 
Then sky emailed me that their is one sky Qtb uhd left which I need to return. Or they will charge me £100. I have no idea what this equipment is. Kindly look into this matter.

To get you some help with this I have escalated your post to the Sky Messaging team who should be in touch with you regarding this via a blue/red chat bubble which will appear at the bottom of this page. It can take up to a few hours to be contacted via this.

This link explains how this works so you need to respond to the chat bubble at the bottom of the page:
https://community.sky.com/t5/Did-you-know/Escalating-a-post-to-a-Sky-expert/ba-p/3711147

When the chat bubble does appear you have 48 hours to respond or it will be automatically closed. This isn't a live chat so replies are not instant.
