Incorrect delivery

Ordered shoes sent them the photo of the spesific shoe, they ask me to confirm with a picture if it is the correct shoe I said yes. Trusting them i just paid the invoice not checking what shoe is mentioned on the invoice as I dit confirm on the picture they sent me. The incorrect shoes were delivered and it is MY fault as I did I NOT DOUBLE check the invoice???? Pathetic IT IS NOT THEIR FAULT. ???????
