The reason they gave a S*** about taking the product back from you is because they do not have much competition, if you were living in a competitive market where every customer's purchases make a difference then that same salesman would have been trained on how not to say "NO" to a customer ie:He could have contacted the city center branch come up with a solution,accepted the exchange of your product and then dealt with the other branch in settling the accounts and voila Carrefour would have one more very happy customer who would probably lure more people to their business.

I personally have had problems with electronic items purchased from Carrefour, not once but thrice,eventually you have to take the product your self to the dealership to get the deal on the warranty, so I have stopped electronics from them, don't know what's the deal on the quality of the electronics they stock.
