Sorry to hear about your MLM experience

I would cancel the credit card and replace it with a new one if they have this information. If its through your bank account, I will contact my bank and explain the problem to them and let them instruct you on what you need to do to resolve this problem. If all else fails, close out that account all together and open up another. Its better to be safe than sorry. There’s always a way to undo a situation. Also I would write to the company explaining my departure from being involved with the company any further just so you can have something in writing no longer giving them permission to go into your account. Its called stealing if they no longer have permission. If you have to, file a police report if they continue, as well as a report with BBB. This should help protect in the event that you need to file a suit in court.
