Excessive duplicate live cards

Hello guys! So, this is the first time i'm pulling for live theme cards, and i saved around 6k to get at least 3/5 illit members.

I didn't had major problems getting live themed cards, but everytime i get one, it's moka. Yesterday i got 2 moka S cards and 1 A moka card. I got a little frustrated so i waited for today to pull again so maybe it'll be fixed, but guess what...i got a R moka card. To clarify i didn't get other members live cards, out of 4, 4 times i got moka.

Is this common? I've seen ppl with 2 duplicate live theme cards, but never 4, much less in this case where i'm not pulling millions of times, i used 2k gems so for me it seems weird. Has this happened to someone else? Should i contact support? What type of inquiry will be this? I'm thinking of asking for an inquiry on bugs and errors but i'm not sure

If i'm just unlucky, what do you recommend on doing with all those cards?
