Lost items I paid for, unsure how to get them back.

I recently re-downloaded this game after havimg not played for a while. After signing in with my Google account I started playing. I chose to buy a few items, including 3 champion crystals. After playing for a bit I received a pop-up advising that if I signed in with Kabam I would receive a free Crystal. I did so and apparently I had linked my old profile, as I lost all the champions and other items I had just paid for on the new account. If I had known that I was able to recover my old account I would have waited to spend money. How do I speak with someone about recovering the items I paid for?
