Help!!

Help I accidentally bought the X-Factor Pack from NBA Mobile 2k18. Is there a way to return the units in a refund? Before I bought the X-Factor pack, I bought some other all-star pack. I attempted to use the NBA Cash that you receive as a bonus from the pack to get a Yao Ming pack but I accidentally tapped the X-Factor pack. And since I already recently bought the  All-Star Pack, it didn't ask for the password and it closed to my homescreen. I logged back in to see what happened and the X-Factor pack wasn't there. 

My IGN is Kai. I have a profile picture of a dog with swimming goggles on. Thank you!
