mychangeaddress.com Bridgevine scam, impersonators of the USPS! Internet

I thought I was changing my adress with the USPS! I was charged $9.95 for an address change with the post office. I thought this was wierd but thought that perhaps the USPS had outsourced this part of their services due to lack of profit. I filed a chnage of address on 12/30/2011. After leaving my old office site, I have not recieved 1 peice of forwarded mail, in fact, my mail still goes to the old address.I will address this with my credit card company, but who is there to stop these scamsters? I did get a confirmation number, but after looking again, there is no contact information except the printed website address on the receipt! Who would have thought?
