Only two are incorrect.

Explanation:

You have done well. The first one would be "yours" instead of "your."

Third one, "so has his wife" instead of "so have his."

to whom may it may concern;

i have recently ordered a product from your online shop. the shipping details read that my order would be delivered by the 8th of december, whereas it was delivered the 13th. i needed the package for a christmas exchange. 

since i paid for overnight shipping, but did not receive the package in the time allotted, i am kindly asking for a refund. the product was just perfect, but i do not believe i should have to pay for a quick shipping if it came late.

you for your time, i hope to hear from you soon.

sincerely,

john smith

buenas noches would be your answer
