Free 2 B U clothing defects

I purchased 3 items from Edgar's in the last 6 months, wore the items no more than 5 times each and now holes are falling in all 3 items. I went back to the store with all 3 items showing them the pattern, and they refuse to exchange the tops for the same items without the slips. I understand the policy, however here is a case of clear damaged goods in the form of material defects. Surely Edgar's can assist me as the customer and deal with this supplier.
