PWZ GW2 missing 50 rainbow stars from twilight chomper pack

i purchased the twilight chomper bundle and it said 50 rainbow stars were meant to be in it but i didnt get them, my friend got them even though they went over the normal limit on held rainbow stars and i also got the 200 stars going over the normal star limit. i had 50 rainbow stars already from doing a few matches today and yesterday & a few months ago so those are the only ones there, none of the opened packs had the 50 stars. i tried contacting someone through ea's support chat and they said to make a post asking for help here
