I seen an add for a free tumbler from IBEX Company just had to pay shipping. And now they have charged my bank account $39.95 for the tumbler. I called the company and they said it was a trial and no where in the add did it state that. Why would I pay shipping to try a tumbler when it stated FREE. They even asked if I wanted to purchase additional tumblers and lids and I said no, even then they never stated that it was a seven day trial. Please help me on this matter
