PosterPass.com Multiple Unauthorized Charges, Internet

I have received two unauthorized charges of $70 per charge from Posterpass.com within the last week. I have been unable to reach the company for an explanation. Because of this I have had to work with the bank to file a fraud report. Even though I went to the bank before the charge actually went through the bank said I had to let it post before I could file a report. I am beyond upset because this has caused all the authorized auto payments from my account to get kicked back. I have not had any dealing with this company since Mar. of 08 and at that time they tried to scam me by sending mutiple shipments of posters at the same time & charging $49 per shipment. I only hope that someone will be able to sue this company for the extra issues and problems their unauthorized payments have caused so many people.
