Sorry to hear that. I guess what is discussed is the Mitsubishi LPC826/836 650nm diode whose secure power is 130mw. Sure it can be pushed to 200mw or 230mw or higher but it will short the diode life very often. We burnt some already with the similar attempt in the lab. 100-130mW might be more worryless. Sure i might also be wrong
Ask for a refund or replacement and they might not refuse it if you didnot reverse the battery polarity or something - this can be detected if you did. Good luck.
