I reckon it'd be typical of most companies, assuming at this point they haven't had widespread reports and info filtering down to individual stores that it's a known fault. If a given store has only seen this issue once to this point, they would assume it's a user accident.
Guess we'll see whether it's a fixed-for-free thing or takes a class action to get to that point.
Consumer protection rarely covers carelessness or applied physical forces (dropping/hitting). The customer claims no such thing was involved but anyone working in customer support can tell you that customers lie all the time. So a random employee made a judgement call but that decision is not final. The customer should escalate it.
