Query: Customer Service is An Absolute Nightmare

I had lost my Viruscan CD and requested via their online customer service for assistance with a replacement copy.After more than 2 months and series of very frustrating emails, I am still without a replacement CD. First it took more than a month for Mcafee to finally acknowledge my proof of purchase. And it's been nearly a month since they last emailed to say that issue is being looked into.Often, when I send a reminder about my unresolved problem, someone new responds and asks me to fill in all the tedious details again to show proof of purchase. Then they forgot all about my emails till I emailed them again.I have never in my life encountered worse customer service than that provided by McAfee. And when I checked on the internet, it seems that I am not the only one with horror stories about McAfee's customer service.I have given up and will be buying Norton instead.
