McAfee - Unable To Cancel Subscription Renewal

I must have registered for a free trial and/or registered with McAfee about a year ago, not realising that auto-renew was on. On the 23/01/2002, $59,99 (R1258,04) was charged to my credit card. I received an email from McAfee to let me know that my subscription has been renewed. This came as a surprise to me. I no longer want the subscription, it's certainly not something I can afford at this point in time. The email explains that there is an option to cancel and receive a refund within 60 days of renewal, however none of the links to their customer support pages work, and the number they provide "is not in use" when dialed. There is absolutely no way to get hold of this company. I've had a look at the reviews that others have posted, and many have experienced the same issue, saying that even when they turned off the auto-renewal, their credit card was still being charged every year, that their bank can't reverse the charge, and that the only option left is for them to change their banking details/credit card details. This is utterly shocking, and such disgusting behavior on the part of McAfee. Not being able to get hold of this company is highly unacceptable. I would appreciate it if someone from this company can contact me to resolve this issue, as a matter of urgency!
