So I bought the Damier Neverfull PM from HI while on vacation. I never wanted a NF, but the Damier version was nice and the SA was convincing with the 'it won't be in the mainlad for a year!' speech.
They shipped it to me (even though it was against technical policy) because I had already paid for it in store and I choose to have it shipped for no sales tax. Apparently they no longer do charge-sends, but just sends are ok in certain situations?
Anyway I've been using it and one of the straps has become unglued and is completely separating (think: one piece of leather is now 2)! When I was purchasing it the rivet on one strap popped off! Of course we noticed that so I purchased a different bag, but this means 2 bags of 2 of this kind fell apart before my eyes (albeit in minor ways)!
I went to my store (Houston) and explained the situation and how I wanted a new bag as this one is clearly defective (less than 2 months use). The obvious problem: none of these bags exist in the US for them to give me and they can't get one! So she tells me they are coming in November and I can get a new one then or have mine fixed.
I went home to ponder my options and decided I no longer wanted to have anything to do with the Neverfull, as I've personally experience 2 quality issues with it and I'm fed up.
I called and asked for a store credit but said they could only exchange it for equal or greater value.

I'm not asking for my money back, just a store credit to buy a Suhali (much more expensive) bag in the next couple months as I don't have $2500 to drop on it now.
What do you guys think? Should I be able to get store credit in this situation? Can they demand the opportunity to 'fix' my bag and refuse to give me a new one?
