Dear V. Mawson,
Thank you for commenting on our product.
These genuinely are 10mm-Pin Casters. They were listed on www.Amazon.co.uk by us at Chellgrove, and as a result we have helped many people who need these unusually sized Casters. Unfortunately, another seller sold against our listing in June 2012 without first checking that they have the correct product. I am very sorry to see that you have been caught out by their inadvertent mis-selling.
I hope that you and everyone else who has been mis-sold in June 2012 have been able to get a refund from the company who sold the Casters to you. If not, we at Chellgrove would like to help you by replacing the Casters you received from the other company with genuine 50mm Wheel 10mm-Pin Casters:
Simply send the Casters to us with some proof of purchase (e.g. a print-out of your Amazon purchase confirmation), and we will send you the correct 10mm-Pin Casters in return.
To obtain our address:
* Go back to the top of the product page and click on our name (Chellgrove)
* Then click on "Default seller information"
* Finally, click on "Contact Chellgrove Customer Service".
This offer is open to everyone who has been mis-sold 10mm-Pin Casters in June 2012. We will honour the offer throughout July 2012 to everyone who sends us a genuine Amazon proof of purchase with their Casters. There will be no charge for this service.
