Melaleuca Independent Marketing Executive

My elderly mother signed up to be a member of Melaleuca, which required she pay a monthly fee whether she gets any products or notThe "points" she receives for the monthly payment can be redeemed but only after she places a paid order of $or moreIn April 2016, we called the company to cancel the membership (it cannot be done online unlike signing up for the membership)We were told to fill out a document, take a picture of it, and email it to their accounts emailDid thatNever received a responseFollowed up three days later asking for confirmationNo responseCalled againThey claimed it was never receivedDid the process again in May, then in June, then in JulyI finally cancelled my mother's credit card from Melaeuca (which had a 24% interest rate!) to stop the automatic paymentsThat got their attentionNow they are harassing me and my elderly mother for payment even though we sent the cancellation form to them again in August AND finally received an email confirmation that said the membership was cancelledBut now they claim it is not and want payment
