hello, my vavin pm is a couple of years old, but i noticed that some of stitching on the handles is fraying and coming apart because it has been rubbing against the top edge of the bag. the top of the bag is very hard and there is no way to prevent the handles from rubbing against it and i'm afraid the stitching is going to come apart altogether soon. has this happened to anyone else? how much will it cost to re-stitch or replace the handles? thanks in advance.
