Horrible

Me and my friend bought the same handbags last year June, it was a shoulder handbag that we use once in a while, since I have only used mine not more than 6 times. The bag has been peeling from day 1 of using it, at first I thought it was just a minor thing, second time using it. Didn't make mucb of it. I started realiing that is getting worse should I use it and it and it would be late. Then my friend asked me about it and it was then that I took it serious. Last week Friday I decided to take both handbags back and was told that they can't replace them as they only have a 6 months quality assurance or something like that. My worry is how is that possible as I don't use the bag daily, I have a few bags that I use daily to work and have been using them way before even buying this one. Am not experiencing the same thing as this one.
