Hi Mrs Newman,
Thank you for your review and we're sorry you feel this way.
Unfortunately we weren't able to alter your order as you got in touch with us after your order was dispatched. We always strive to assist customers as best as we can and whilst refusing delivery at the door is advised for the quickest return, we also offer a 60 day returns on unused products, as per our policy.
The sizing and usage recommendation is available on the product page on our website. We're sorry you missed it before you placed your order.
Please get in touch with us at firstname.lastname@example.org if you require any assistance.
