You have been here long enough to know that there are very strict (stupid) defamation laws here, and if you say anything negative about someone, or a business, they can, if they want, bring defamation against you.
So your saying that something will arrive from Lazada with parts missing or no plug COULD lead to the vendor getting pi55ed off, saying that your statement has hurt his business, and do it. As you say, for such a small item, probably not, but he would be within his rights to.
