I called Colon Cleanser 3000 because they billed me $4.95 for the trial offer, and I never received it. The phone number on the credit card charge identified the product. When I called they told me that they never charged me. Asking to speak to the supervisor, he said the same thing. He wouldn't respond to my asking him how it got on my bill. He hung up on me. Not trusting them, I called 1-888-895-1159 to make sure they cancelled me. I might have to change my credit card number so this doesn't happen again.
