damaged watch from day one

We bought a fossil watch in 2013 from Carnival mall Edgars.. ever since we brought it its been giving us hassles.. they refused to give us a new one and send it for repairs every time.the first month the links started falling apart not long after the inside stop working.. its back now again as the watch inside keep moving around .I don't want another repair as they dont fix it really but they refuse to help me other wise.. the worst is Fossil rep was there and he said nothing wrong..worst service ever.. one doesn't pay 2500 for a watch to be more in for repairs than anything else.. disappointed
