No? If I went into a store to complain and my first words were "what kind of shit have I bought here?", then I don't think I'd have any cause for complaint if I were forcibly ejected and told to come back when I'd learnt how to behave myself. Same should apply online.

If the store then came to your house and confiscated your product, you absolutely WOULD have the right to complain.

The store owner could go to jail, because that is called theft.

Screwing over customers has a cost.

This story went viral. And now this business is going to receive hundreds of negative reviews.

The product wasn't confiscated though, only the service was cancelled, and a refund was offered for returning the product. This is the main point a lot of people are missing here.

As it stands, this is how ANY court of law would see it as well.
