If I purchase a pre loved LV bag and it has the stamp mark showing that it was an employee purchase, e.g. the round circle or the V with a circle, will they be hesitant or refuse to perform repairs on it in the event I ever want to replace the leather or have anything repaired? Also, if it is defective, will they not allow exchange for a store credit? Like for instance the peeling canvas issues on 2015 mono canvas etc.
