Query: Parts of this product are poor quality & the seller's return policy is even worse

I really like this shopping cart bag EXCEPT that the zipper that holds this bag together (when not in use) broke after 2 uses. Since the 2nd use happened after the end of the 30 day return policy AND since I had already used the product (of course I did! how else would it break?) the seller would not accept a return. BabyAge was the seller I purchased through on Amazon and I DO NOT RECOMMEND THEM. The product of course also was at fault so I also contacted BuggyBagg and after a couple voicemails & emails to them, I did not receive a return call or return email.
