Review on 4-Foot National Tree Company Pre-Lit Artificial Mini Christmas Tree - Green Kincaid Spruce with White Lights & Stand by Joseph Lang

I received this 4 foot tall pre-lit tree yesterday. I plugged it in for maybe 3 hours when the top half of the garland went out. I tried checking the bulbs and replacing the fuse but they still didn't light. When I got to Revain and saw the product support option, I contacted National Tree. I had to wait and was finally answered by a rude and unhelpful customer service representative. Since the 4-foot tree is clearly "not under warranty," he said all he could offer me was "a string of lights, but I could just buy them." I could barely finish a sentence and he didn't interrupt me or seem to be trying to pick up the phone. Guaranteed or not, I have not paid for a "pre-lighted" tree to have the lights go out within 3 hours of first opening the tree.
