If you bought from a business seller, there will be contact details on all of their listings which may include an address, an email address and a phone number.
If you can't contact them through Ebay, and not all sellers accept messages, then use an alternative method.
If you google 'their online name' + Rainford + contact. you will find their online store and an email address.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
