Sent off for a free sample which was not free.The company have continued to collect payments from my account without my consent. I only agreed  for the first sample of acai lipo  which was free they have now taken 2.99 62  so far which i have had refunded up to now from the bank. They have now managed to get 62 from my cancelled card after it was cancelled and the bank seem powerless to stop it.Have been told they can take what they like as its classed as a rolling debit although i have not signed for them to do so.Dont no what to do next they have no e mail contact and the phone number given just rings. louise devon
