Hi,
I sent to the support today`s bank statement. You can find bank address there, last digits of credit card, my name, date of charge, amount, currency, the fullest available reference line etc. I can`t give you any more. It`s more than enough to identify if I got charged namely by Avast.
Otherwise I assume this is a suspicious fraudulent transaction, then pls inform me asap and I`ll ask police to start investigation.
