E-HealthWeb.com – Takes money from my account without permission

I ordered some pills from E-HealthWeb.com from an advertisement that I saw in a newspaper and I all I supposed to pay for was shipping. So, I gave them my debit info to pay for the small amount of postage and the pills arrived a couple of weeks later. I looked at my bank statement a couple of months later and found that they had been charging me a fairly substantial amount of money without my approval. I called E-HealthWeb.com and they person who answered the phone was very rude and told me that I needed to read the fine print which says that they are going to start charging me. I looked at the add again and there was no mention of a reoccurring fee.
