Thanks for the answer!:) but I payed through Liqpay;is it the same?!
If you payed through Liqpay the money destination is PrivatBank (the owner of LiqPay system). But the comment with the payment is "AChat premium subscription". If your friend has access to you bank account transaction history then he will see this description. But as I know that information is highly confidential and not all bank employees have access to it.
You can contact achatpayment customer support and ask change payment description for your future payments.
