Battle pass 2s

Good afternoon, I have a problem with my combat pass.

If in more detail, I did not manage to close the pass of the 1st season, there were 900 coins, by the release of the 2nd season, I bought coins on a third-party platform, in order to purchase a battle pass, the pass bought everything is good, actively started playing, but I noticed that some awards, in particular coins, were empty cells, I thought it was a visual bug and the rewards would still be added. Later, this bug disappeared and the coins began to be credited. as a result, I should have 600 and 300 coins (remnants from the first season, I had 900 and bought 500-1100 for the pass). Currently, I have 400 coins, but I should have 900. I received the first 100 coins a couple of days ago. I haven't made any purchases in the store. I've contacted the support team, but they can't add the coins to my account. They suggested that I submit a request, but I'm not sure why. Waiting for an answer.

I also created a topic in the bug report, but I don't know where it belongs.
