Hi! I'm considering buying a couple of LV items (a bag and an SLG) preloved from Fashionphile. I hope to never have any issues with them, but if I do (for example, cracked canvas or glazing), will LV do a repair for me if I pay for it? Some boutiques require proof of purchase before they do a repair, so I don't want to run into any trouble at an LV boutique. Thanks!
