The recorded bitcoin payments I made within the 10 minute time limit add up to the full amount of the order but the website said that I still owed .00000000000000017 btc.  It was a problem with the website but at first Roberto said I didn't pay in full and now that I have showed him proof that I paid in full Roberto says that the order I placed was for a totally different amount at a totally different rate.  He says that I made up the original order and he doesn't know what I'm talking about.  He's lying because I still have the details saved to my hard drive.
