defective product

I purchased both the Whirlpool Duet washer and dryer from Lowes in January 2011. I have a full warranty plus I purchased the 4 year extended warranty. SInce the first day they were installed, the dryer has continued to ruin my clothes. It pulls and snags the fabric of my husbands shirts. I have had 4 service calls on this issue since January and it still tears up everything you put in it. The last tech said he didn't know what else to do and suggested that I put my wet clothes inside dryer bags before I used the dryer. How ridiculous. Don't buy it. Connie, Apopka, Fl
