Quilted Sweatshirt

First off the good...the fit is nice and overall it's very comfortable. HOWEVER, the fabric on this pullover is very low quality. Within just a few months of wearing it, I have holes in both elbows. There are also holes opening up all along the seams. I'm not taking this pullover hiking or getting snagged on things. I wear it mainly in an office setting and at home. Despite relatively gentle wear, the fabric is just not up to snuff. I tried it take it to my local LL Bean store to see if I could use the warranty for a refund, I was told that the holes were "not a manufacturing defect and were normal wear and tear" which is ridiculous because the holes started after 5-6 months of regular use. Pity because I really wanted to like this sweatshirt but the poor quality doesn't justify the cost.
