Scammed by RiseZone

Was just scammed by a company called RiseZone.  I was having issues renewing my Norton and a number popped up for technical support.  These people led me to believe I was speaking with techs hired by Norton.  I gave access to them on my computer and they showed me all the issues which i knew I had and told me they would fix them and then Norton would download.  I was feeling uneasy but they seemed to know what they were doing as I watched them control my computer.  After showing me a note with all the work they would do they said it would cost $199.  They tried to get me to a payment page to enter my credit card but because my computer is so messed up it wouldn't work.  He said i could pay after.  I started feeling uneasy and decided to look them up on my phone and everyone was warning it was a scam.  Even their webpage was messed up.  I asked them to stop and they started getting mad...I disconnected them from my computer and then they tried to call but I did not answer.  All of a sudden they popped back on my computer and changed my password and I have no connection to my network.  I then was able to get a hold of a real Norton rep and he said I needed to call HP to figure out my password.  HP now needs to clear my computer and I have to start over.  Thankfully they can save all my pictures.  Then I have to call Norton and they will check my computer.  I almost made it 40 years without being scammed.  I should have listened to my gut...I just really wanted my computer to work. BEWARE people!!
