Proof of delivery for e-products delivered

[Buydeal_eu]

Hi,

I sell only e-vouchers in my website and the delivery is only through email and SMS. When a user claims 'Item not received'  but actually delivered. What kind of proof is accepted ? The email and SMS sent proof was not accepted and the case is closed in favour of buyer. I would like to know anyone else faces this issue and what kind of proofs are accepted to make the case in favor of Seller .

Hi @Buydeal_eu, we hope you're doing well! 

Here is the information or evidence you can provide for intangible items:

Purchasers email to where the goods were delivered.

Date and time when the goods were downloaded/delivered

Proof that your website was accessed by the buyer.

Purchasers IP Address.

Hope this helps! Stay Safe.
