Query: Poor Service from Rival

I purchased this product and then, before using it, happened to see all of the horrible reviews here on Amazon. I called Rival to see if they had perhaps remedied the problem of this "slow" cooker getting way too hot. Given the over-the-top bad reviews here, I figured they must have had a ton of complaints and maybe had done something about the problem. After waiting on hold forever, I finally talked to a young man who claimed to never had heard of this problem (???) and then mumbled, "Well, I mean, you know, I'm with the company so I can't say anything bad." What? What horrible service. There is no way on earth they don't know about this problem. They just must not care. So, I told him, that if they were not aware of the problem then they must not have fixed it so I'd be returning the crockpot. How disappointing!
