Hi
£52.99 has been debited from my bank account. I have no email confirmation or order confirmation. In fact, I had no idea was Avast was until I googled it. Can someone advise on what I need to do ? I have no idea what product it is either but I would have least expected an email of some sort.
Thanks for any help !
