I called the Flex Seal telephone order number and went through an automated phone order process. I ordered 1 can of the product along with the free can with shipping charges offer. Before I could get a confirmation of my order and the cost, I was put through 15 minutes of additional advertising offers and finally hung up. The next day I called to verify my order and was told I had ordered 2 cans and the special offer meaning I would be charged and extra $49.95. I asked them to cancel the order and they claimed they could not. They suggested I send back the extra cans for a refund and gave me return numbers, promise of a return label and other things. Talking with the supervisor did not change the problem. I would not encourage anyone to work with this company, even if the product is great.
