I agree with everyone here. Be very proactive about this. Contact your bank - go there in person - go to the top - manager or whatever.

Be sure to write down the date/time/person etc. that you talk to as you try to get this resolved.

Take the time to write down all of the events in order from the time you contacted the vendor, who you talked to - date of shipment - date of charge.

They must be stopped - because obviously they are doing this with other people too.
