Sky Puck Return no received

[JayJay9]

I have returned my sky puck and have a confirmation it has been sent and an acknowledgement it has arrived somewhere at a warehouse. However sky keep texting me to send it back. I have a proof of despatch from the post office.

@JayJay9 give Sky a call. As you have proof of postage it should be straightforward to sort out.
