Ordered through guest account. Received no email confirmation. Took photo of order number as eBay have done this before. Order arrived and it is incorrect. Ebay say I need email to arrange return. I do not have an email. I only have order number. Ebay say they will resend email using the order number. No email arrives (checked junk). Contacted company and they said I need to arrange returns through original email, again- I DO NOT have ANY email. How do I arrange a refund/return when the only information I have is the order number and the incorrect item. Please help.
