I looked at the offer and the free trial and decided against it. I was surprised to be charged £9.95 on my credit card on 6th Feb and 6th March. I believe my Apple account was used to deduct funds. I checked my Apple account which informed me the Total Adblock was free and no invoice had been issued. I clearly believe this to be a criminal scam and will have to get my bank to refuse these payments. I have not experienced any change in ads on my computer.
