網購沒領,會不會被告

無畀錢,對方當然可從民事上控告您的,因是雙方的承諾,在法律上一定要遵守的。

Let me put it this way:

When a party breaches a contract, the affect party can always sued for damages or specific performance.

So your friend can be sued.

The real issue is will the seller sue the buyer or not. Usually, a lawsuit will not be initiated unless the value of the transaction is high (like real estate property).

So your friend should be fine (even he/she is wrong).
