Calm down pal. If you ordered from Lazada they have a guarantee, nothing to do with the seller. You got a warning from the platform for not accepting a delivery and quite right too. How do you know he didnt get any hassle and loose out, just because he still delivers proves nothing. You posted on a public forum so its up to me if I comment or not.
The problem with people like you is that you try and apply western standards and processes when they don't apply in Thailand.
