Hi Ted7,
Thanks for your post and welcome to our community.
If we don't receive equipment back within the required time, a charge can be applied to the account.
Once the equipment is received however, that charge is removed with a credit.
Therefore, no refund would be produced or owed to the customer, this credit just cancels the charge leaving a zero balance.
If you've actually paid the £40 equipment charge however, and this has been taken from your back, that would be different, and a refund would then be sent.
I'll send you a private message now so I can check this for you.
Please look out for the envelope in the top right of the page and pop back to me when you can.
