Merged accounts and lost point

I received a prompt to merge my accounts, but the in-game store does not show any points, preventing me from using them in the game.
I need to transfer the points under one account to another or fully merge the two accounts. However, I have sent emails but have not received any responses.
I need these points to purchase the discounted stash tabs that are currently on sale in the store. This promotion only lasts for three days, and if I miss it, I will have to buy them at full price.
Can GGG please help me with this?
