Why doesn't the remote work for the Android box when I only had the equipment for 3 months?

[AC Question]

The remote control was working all day today. Towards the evening, my son wanted to watch another episode of Teen Titans and it didn't work. We went out and brought new batteries which was funds we didn't have to spend, but spent it to see if that was the problem. The remote is not working still. For the amount of money spent on this equipment one would think that it would work for awhile, at least more than 3 months. What can I do? Is it possible for the company to send us a new remote? I don't feel this is fair to purchase equipment that breaks within 90 days of usage.
