Pins keep falling off from links in strap

I took my swatch to the Clearwater branch for a strap re-adjustment. The strap was readjusted while I waited. On the following day, 3 pins holding the links together fell off. I took the watch back and was told I could fetch the watch in 3 days. When I went back, the pins were not inserted properly (they were sticking out of their slots in the links) and when I queried this, I was told that there was nothing wrong, the watch was fine as is (confirmed by the store manager) I took the watch home and the pins fell off once again. I called the Swatch head-office, spoke with Michael and was asked to take the watch to the Cresta branch, which I did. When the watch was sent to head-office, the strap was replaced but the face now had a huge scratch on it. I was told that this was the condition of the watch when I dropped it off but there was no proof that this was the case, since I was not given a slip with these details. I refused to take the watch back in that condition and said that I would be back since the manager was unavailable on the day. I was called a few days later and told that the scratch had been sorted out. The strap needed a size re-adjustment which was done in my presence. The pins once again fell off a day later. I once again, had to go back to the Cresta branch and the watch was once again sent back to head-office. Three weeks later, I called to find out what was going on and was told that the watch was back at the branch, however, the fault of the falling pins was mine since this was attributed to wear-and-tear. Let me remind you, that this strap was 5 days old. I called Michael at head-office once again and he only agreed to change the strap (to a completely new design) when I questioned the quality of the "new" strap that Swatch had put on only a few days earlier. I was told that the Cresta branch would change the strap at Swatch's expense. When I got there, I had a choice of only 4 straps, none of which I liked but was forced to choose one, since this saga had already been carrying on for about 2 months. The new strap size had to be re-adjusted and in confirmation of the pathetic service received from Swatch, I now have a watch with 5 links on one side of the watch face and 3 on the other. I guess that this last fault lies with me - I should be supervising the staff who work at Swatch and making sure that they actually do their jobs, after all, I am not a valued customer.
