changemyaddress.org or net Total scam!! Guaranteed refund is a lie internet

I was on the official USPS website and I clicked on change my address. This company is what came up next so I assumed it was a part of the USPS. I was a bit confused as to why they needed my credit card info but since it was only $0.01 I kind of reluctantly entered it. After I did that I started reading some if the small lettering and saw that it said they would be charging me $40 for a service that the post office does for free!! So I looked for how to get a refund bc it said they would refund anyone's money by just emailing them.

Only there is no email address or any way if contacting them at all!! I went to the BBB website and there's a bunch if complaints about this company but nothing is being done to stop them. Reason being bc they can't find them. If no one can find them then why aesthetic still able to conduct business here in the US or anywhere? Luckily I called my credit card company and they quickly cancelled that transaction or I would have been stuck paying these scam artists my hard earned money. The USPS NEEDS to look into this bc I was lead to them by being on their website! Not ok.
