I have a different problem with my 2.55. The thread that binds the flaps together at the corner came lose,I didn't even carry heavy stuff of use the bag often. I bought it back to Chanel to fix but they did such a bad job with it. The stitching doesn't even match the other side. It was buggin me so much that I took it apart again and got my mom to fix it. She did a much better job (she is a professional) than the in house seemtress at Chanel.
