Should my Neverfull really look this way just after 3 months?..

Hm, yeah I've heard of Peeling Ebene straps before, but that's no excuse. Take it back, we pay a lot of money for quality bags and that's just not up to par :nogood:

Good luck, let us know what they say!
 
Yes, definitely take it back and see what they say BUT, if I was an SA and judging from your pictures, my first question to you would be, "how do you store your bag - it looks like the handles are stored bent over into the bag or bent back."
