I purchased a Pochette Metis a couple of weeks ago and the lock is continually catching on the end and it's very difficult to get into the bag. I've found out it should just ping open which it doesn't. It sometimes stays shut, sometimes gets stuck at the end but overall takes me ages of fiddling about to get it open and I have to tug on the little flap......not good!! If I'm in a shop I need to leave the bag open or it will take me forever to get my purse out Has anyone else had this problem? I'm just hoping there's a knack maybe? If I contact LV will they be able to just replace the lock if they decide it's faulty? They are all sold out in cream and I don't want it replaced for a different colour.
