Ticketmaster — Additional insurace charge

I purchased a ticket on the TicketMaster website and was charged an $7 for additional insurance coverage frin Mondial Assistance without my consent. This is either a very serious bug on the tickemaster website that should be fixed immediately or a scam. Personally I think a 20 percent charge for insurance for something like this is not a good value, but to be charged without my consent is very irritating and is bad business for both Mondial and TicketMaster. Mondial graciously reversed the charges without a problem but this could have easily gone unnoticed. How many customers have lined the pockets of Mundial without even knowing that they have been charged ?
