Konami eFootball Negative eFootball Coin Balance After Refund

I bought 550 eFootball coins in the game eFootball, but later decided to return them and received a refund for my purchase. Unfortunately, my account ended up with a negative balance. I was able to regain the coins through gameplay, and now I have a total of 20 eFootball coins. When I attempted to add funds to the game once more, the transaction was not authorized. I kindly request that Google Play address and resolve this issue. I'm curious to find out if I've faced any penalties. I've been dedicated to this game for quite a while now, and I've invested a significant amount of time and energy into advancing my skills. I really don't want to lose all of that work. I kindly request that Google Play addresses the matter concerning my negative eFootball coin balance promptly. Additionally, I would greatly appreciate an explanation as to why my transaction was not approved. I'm also curious to find out if I've faced any penalties.
