Bad business behavior

The rating relates primarily to the behavior of the seller.
I don’t use the plugin because it is not what I need. According to the law, you can cancel an online purchase within 2 weeks without any problems. The seller refused this. I will not take any legal action because of the small amount of money, but at least the review is necessary. If someone doesn’t follow business principles, then you shouldn’t do business with him. I hope this saves others problems.
