Complaint Review: DAZZLEWHITE PRO!

I ordered the free trial, not realizing I would still need to pay $79.28 if I use just the trial. As soon as I realized this, which was on the day I received the trial, I called and canceled future shipments and said I would return the unused product immediately, which I did. Then, I got a charge on my account of  $48.92 from AccessCleans, another DBA for DazzleWhitePro. When I called to inquired, I was told there must have been a glitch in their system, so they sent me the dental trays and charged my account for this unordered product without my authority. I was so angry and told them I wanted my refund immediately and I had better not be charged one more thing from there company. They told me it would take 5-10 days to process a refund. They did process the refund in about 4 days; however today 10/3, we noticed another charge from HealthSmile, still another DBA for DazzleWhitePro. Oh my gosh!! I called and told them I had sent back their trial a long time ago and had canceled all further orders. Sergio, their csr, ask if I had a shipping return receipt, which I did, and gave him the number. He looked it up and said he would issue a refund within again, 5-10 days. I asked when they had received the product back from me. He said 10/21/09. This was nine days ago. So, why did they still bill my account?? He said because it takes up to 10 days to process in their warehouse. Okay, now they have pushed me too far. I did everything not to be charged and they received their product in plenty of time. They even charged me for a product I never ordered. My question is how can they get away with this??
