Owner called me IGNORANT.

I called Mohawk Garden Market to inquire about returning a quite expensive tree that I purchased last year that had died over the winter and was told they did not offer a guarantee and would not return the tree. I obviously questioned the policy, given that it was an expensive item and the majority of garden centers offer some kind of guarantee or exchange policy. When the man did not seem willing to help me, I asked to speak with a manager, to which he told me something along the lines of "Fine, but they're going to tell you the same thing. I'm actually one of the owners, but I don't deal with customer service." Obviously being frustrated by this, I replied "Clearly, since you severely lack it..." and his reply was "Yeah, well you're ignorant too," and he hung up on me. What?! Since when does an unhappy customer (and I should note that although I was frustrated, I was very calm) deserve to be called names? So, point of the story is, not only do they lack a reasonable return policy, their owners like to name-call. Real professional....
