My mom has an 20+ year old LV wallet (Porte Tresor International in Brown Monogram) and hers is stuffed with nearly 20+ CC's in there. Each of the CC pockets had about 4-5 cards stuck in each of them! It's been stuffed like that for more than 20+ years. The card slots were horribly stretched out and the edges began to come apart. She took the wallet to the LV boutique to inquire about repairing the wallet. The SA offered to ship the wallet to their factory in Europe at a cost (I can't remember the exact amount, sorry). It would take several weeks for repair.
The wallet would have to be completely taken apart and replaced with new canvas materials. My mom was hoping they could at least "glue" the edges back together, but apparently that wasn't the case, since the wallet is basically unrepairable. She didn't believe the first SA so she asked another SA. Unfortunately, the second SA said the same thing. She ultimately decided against fixing it and swore to never buy any expensive wallet or any LV Canvas again.

The SAs were very sweet and helpful, though. Some of the girls in the LV forum didn't seem to have too much trouble getting their SA's to send their bags/accessories off to repair.
She's still using that same wallet right now, or at least, until it completely falls apart on her. Last I checked she still has that wallet stuffed with all her store cards and credit cards, receipts, coins, all that crap. It's literally bulging out and making her purse feel heavy. That poor wallet.
