Till Times Up review: Charge added to antenna order

A $15.95 charge was added to my charge card the next day after my order was delivered. I have read all the information on the terms and conditions on their web site and I see no information about a reoccurring charge. I would like to return the order, and there is no information as to how to do that. No address, nothing. Their ad was very specific about a 30 day return policy if not satisfied, but the ad is no longer available.
