Upon accessing the Vietnamese lesson system, students are kindly requested to check the system thoroughly.

In case there are any issues with the lesson, please notify KNOCK KNOCK VIETNAM immediately for prompt assistance. The refund costs will be agreed upon by both parties.

Since Vietnamese lessons do not fall under the category of products that can be warranted/maintained, KNOCK KNOCK VIETNAM does not apply its warranty/maintenance policy to this type of product.
