Hello ShM1.
Thanks for your post and welcome to our community.
We don't have a return address as such as they get collected by Yodel and sent to the nearest collection depot.
Did you get a receipt when you sent the equipment back? If so, There will be a tracking number on the receipt.
When did you send this off, as it can take around 10 days in total from being sent received and scanned and removed off your account.
If you like I can take a look at the account for you from here?
If you don't mind, I will need to send you a private message to pass security.
If you can check the logo top right of your screen that would be great.
Regards
Gareth_L
