Ok. I think I understand your problem. You must have a credit card linked to your cloudmining account. As you tried to make payment, you accidentally selected another premium option which requires you to pay more. Hence the funds amount to 20btc which get sourced from your credit card. You have two way. Immediately call up the website and told them you want to cancel as it was not your intention to get the package. Or, get advice from your credit card company on how to proceed further with this. I'm sorry this happened to you.
Lol. What?
Since when you can use credit card to pay in bitcoins? Read the previous posts, OP posted blockchain tx id.
He already contacted customer support and is waiting for decision.
