i took my classic jumbo out today and when i was getting it ready to be put back into it's dust bag and box, i noticed a part of interwoven leather was loose from the chain. I've only used this purse 3 times or so, but i haven't done anything strenuous to it, but maybe it just wasn't perfect from the factory.. at the same time, i was always thinking about exchanging the jumbo for a med/large flap.. so i was wondering if i already took the tag off, is it still possible for me to exchange the bag for another one? Despite the price difference now (since mine was bought pre-hike). and if not, and i am forced to repair the bag at chanel... how long will it take? thanks!
