Hi Ian,
I'm sorry about the issue with the clips. We haven't heard from you, so we haven't had an opportunity to look into this and resolve this for you.
Our contact details are on the delivery note, please could you email me a picture of the clips that are fitted to the mats and a picture of the studs that are fitted to the floor of your car?
We will have alternative clips to sort this and can get these sent out quickly for you.
Kind regards,
Chris.
