Example Output: negative

Example Input: It was spilled all over inside the envelop when it was delivered, no safety seal. When I tried to request a refund, it said not eligible for refund, contacted seller and sent picture, no further response. Posted review twice but nothing showed up, what is going on?!
Example Output: negative
