What is the purpose of providing evidence during a discussion ?

here your answer

Explanation: Providing evidence as part of your arguments in a discussion helps your statements and claims to be more than opinions, but instead, such arguments are turned into facts, that can not be debated and can help you support the way you present your ideas in a discussion.

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
