Second comeback on my repair under warranty

I bought a Diesel Watch from American Swiss for almost R3K, thinking that this would mean that its a good watch and I would get good after sales support, a little over 16 weeks ago I took it in because one of the silver hour pins on the face came loose, I waited 8 weeks to get it back, when I cot it back i noticed that the tech had bent the minute indicator arm, and it kept getting stuck, so I took it back again, another 8 weeks went by and now the 2 for the 12 is loose as well as 3 silver pins an the face, now it means that it has to go back for another 8 weeks, I bought this watch in September 2014, if it goes back again now, it will mean that it will be in for 24 weeks in total, 6 months in for repair???? really????? I ask you is this fair for a watch this expensive? should I not get a refund or at least an exchange for a new watch????
