Chella Professional Skin Care Sent free, postage-only sample, then sent additional product for two months, putting $90 on my credit card each time. Webberville Michigan

I responded to an advertisement to get a skin firming serum Chella product free, paying only for postage of under $7.00. I received the product. A month went by and I received another product, then later noticed the credit card number I had provided to pay for the postage on the free product had been charged $90. I didn't bother, thinking it was a mistake they would correct as I had not asked to be sent monthly supplies of their product. Then another Chella skin firming serum product arrived yesterday. This one had an invoice for $90 enclosed with a notation that it was prepaid by credit card.

I've been calling the customer service number on the invoice (877) 492-7637 but it rings busy during the dozen or so times I've called.
