I used a web site that was suppose to convert a file format for free. The web site is CADMonster Srl. I uploaded my file and they converted it - or that is what the message said. But to download the converted file they wanted $5.00. I did not download any file and closed the web page. Not I received a invoice for $5.00 from this web site. (I wonder how they knew I had a pay-pal account?) I did not receive any file from these people and the conversion was suppose to be free. This is a scam and I want to know how to remove this invoice from my account. Thanks to all.
