Query: poor construction

i got 2 of these wetbags as gifts. my blue one had the stitching start unraveling after less than a month of use. the red one had the zipper pull fall off after 4 months. both of these leaked thru the PUL (and not with soaking diapers inside). they are a great size for travel, but i can't use them anymore b/c they are falling apart.**UPDATE: i tried to contact manufacturer. they said i must contact the place i purchased the wetbags. Amazon said i could not return unless it was in new condition. if it was in new condition, i wouldn't need to return. they (amazon) suggested i try to sell the wetbags as "used" on their site. anyone want a non-functioning wetbag?
