Query: Piece of junk

I got this for a Christmas present last year. Worked fine for a couple of months, except sometimes the coffee wasn't really hot. Coffee tasted good, though. Then, one day one of the pods exploded and after cleaning it up, I tried to make another cup. That's when the water started running and running and running. So I called customer service, and they sent me a new one. That worked well, until Monday when nothing worked on it. I pressed the button, and nothing happened. Switched to another outlet, still nothing. Call customer service again and they said they were retooling it and a new one wouldn't be available until August. She said they had had lots of "major" problems with this machine. I asked for my money back instead and will try to find a different one. Maybe I'll check out Gevalia or Senseo.
