Need help about this

Hello, I’m interested in whether anyone had problems during the purchase. Yesterday I took three things on Diablo Imoratl, Proggy x2 for 18.99 and batlle pass for 5.99. Yesterday I received one proggy and the rest was not from my card, it took money for the entire purchase and in the game I what I took was locked, I contacted blizzard about the problem, they said that there was a mistake in the purchase and it didn’t go through, so I contacted the bank, they said that the purchase was successful, so for 43.97 euros I only got one part in the game that costs 18.99 euros in my account that all three were purchased properly, but only one was delivered to me. I would be grateful if anyone could help me with advice or something
