Refusing to supply loose Infinity Pendant

I got an Infinity Pearl Bracelet as a gift for my birthday in June 2018, the Infinity pendant got lost as the clips are not that great, now I enquire to purchase the pendant, only to find out that they are not willing to sell the pendant separately I need to purchase a whole new bracelet. I don't even have the bracelet two months so why should I purchase a new one if the pendant is loose, surely that can be replaced? Or refer me to where I can purchase the same pendant because now I cant have the complete pearl set.
