Fulfillment Center review: fraud/unauthorized charges 1

This "Lifestyle Program" was offered to "try for shipping only $4.95. Instead came multiple shipments charged and there is no way to get hold of them. I spent alot of time on "hold" (telephone) and pushed the right buttons to have this cancelled (I thought) and today I get another shipment with $44.90 charges. The paperwork says they will not refund if sent back without RMA (Return Merchandise Authorization) but...again...it's impossible to get to a person.

What to do?
