First thank you so much for everyone's feedback. I have learned so much from everyone's replies. Every single one of you rock!!
I went to the bike shop today and addressed my concerns. They will not trade out the bike as it is now considered used. The manager, who also sold me the bike, said that is why they do the fitting to make sure the bike is the right size. I was speechless. Other than telling me to decide which bike was more comfortable and raising the seat, he did not really do a fitting. I really wanted to remind him that he spent more time talking to my SO than talking to me about the bike but I kept my mouth shut. No sense in alienating him or the shop. He did say that whatever adjustments that need to be done, including shortening and sanding the stem to adjust my reach, is completely covered for the first year. He also said to keep riding as my comfort level may change as I get use to the bike. So with all that said it looks like I will be keeping my bike and I'm completely okay with that. I've grown kinda attached to her!
