Faulty Bag

I received the cross body sling bag as a gift and it was bought at the Jeffreys Bay store on the 22nd of October. When i received the bag the zip was faulty. Last week I went to the Promenade Branch in Mitchells Plain and they returned the bag gave me a new one. The new one now also has the same problem. The same bag with the same problem. I really like the bag but the issue with the zip thats faulty is now not on.
