Misrepresentation then Getting money back

They advertise get a free sample to try but do not make it very clear that they are just going to continue to sent it to you and charge your bank account.   I was livid as I am not interested and wanted to discontinue.  When I called they already had sent another and billed my bank account.  I obtained a Return Merchandise Authorization and was then advised return when I received which then  cost me almost $15.00 to send quickly and have a tracking number.  They received it and I waited a week and called back.  At that time the agent I spoke to advised they had received and I would receive my refund within 5 business days.    It is now 11 business days and I called back and spoke to a different agent who could not locate the return using the tracking number and gave my lipservice and said wait another week.    This is absolutely a huge scam and I wonder how many people simply walk away.  This product needs to be removed from sale and this type of scams against the public stopped.   There are many great products available every day at legitimate stores.
