Loral Langemeier Wealth Foundation -Preimier Mentoring Her company is digging a hole for me Internet

I heard her on a radio interview hawking her "free get rich" materials.  I was down and out; I have started to dip into my 401K for groceries so hearing this on my way to church, I thought (or prayed) that this was a very good omen.  So I called to order her book and CD, gave out my Amex card for the shipping and handling.  Next thing I knew, I was getting monthly deductions from my credit card.  I tried to call Loral and company but I could not get through.  I then had Amex stop payments after months (at least a year) of this and recently, I have been receiving calls from a collection agency on their behalf to collect over $300 of back payment.  I said I had no use for the program but was told I was on tape agreeing to all they said so I have to pay up no matter what.  I was also told that this amount would continue to go up and accrue unless I settle now.  Aaaaaaaccchhhh!   What have I done???
