New watch, worst quality

My 4 month old Fossil's "leather" strap is disintegrating at such a rapid pace, I fear it will fall off soon. I contacted Fossil SA HQ and Watch Republic and no feedback. I am shocked and appalled by the quality. And I am not going to hand it in at a shop and wait 6 weeks. I want it fixed same day. My husband didnt spend thousands for a watch of such terrible quality. If I wanted a broken watch which needed to be repaired with a turn around time of 6 weeks I would have bought one at a street hawker.
