Account capabilities have been compromised. Problems with purchase

[Боже дай мне Swag'u]

Hello everyone, everyone who reads this please help my friend, he has this problem I quote: From the beginning threw from the bank A to the stim, and everything was normal. After decided to throw from the bank B to stim, threw the first time all was normal, threw the second time all was normal, when threw the third time 50 hryvnia I had a problem that the bank wrote off the money, but here on stim they did not come, tried to request a refund through the bank B, nothing worked, the money and did not come and they were not in styme, then threw the fourth time from the bank B 50 hryvnia, the card was charged but on styme they did not come, then went to the history of purchases and saw a message saying “Purchase is considered”. Went to the settings of stym about the account and saw that you need to confirm the bank account, confirmed, and then bought a few skins in CS2, after about 30 minutes came a message in stym say the possibilities of the account were violated. And after another 30 minutes I couldn't start multiplayer game in CS2. After I wrote to support and this is what they answered:

Now I do not understand what to do and how to solve it. (Comrade's region is Ukraine)
And also in the history of purchases in the comrade is not displayed the third transaction through the bank B, and the fourth after confirming the bank card within an hour was written off.

I'm sorry, I did it through a translator. "stim = steam"
