total service failure

i bought a watch which was not working in a city different from where i am working when i tried to return with emailed receipt copy they asked original to be presented where i bought the watch but they will courier it back to original store. when i got to store having requested my wife to present a slip to purchase shop the two branches argued about who should pay the courier fee of around R126 and told me i must drive 456km*2 to return the watch which wil cost almost 20 times that fee. i am still carrying a watch which is not working to date.
