My Phone Support Consumer Soft Scam - DO NOT GIVE THEM ACCESS TO YOUR COMPUTER!!

Called the company and was having issues with PowerPoint.  I was told that they are Microsoft at first then asked agan and they said they were affiliated with Microsoft.  I asked if they were contracted with them and he wouldn't answer he kept saying the same thing.  (this was after when I was on the phone with them).  I didn't realize it at first they werent a coworker looked on line for Microsoft contact number and this came up.  We called I told them my issue and they wanted to charge $99.95 and I needed this help right away for a deadline.  The first guy said he needed access.  Once he did he started to try to put their software for a help on my computer without permission and I said what are you doing and he said what he was doing and I said I didn't give you permission to do that!  He said oh ok let me remove it.  I said I need the technician and then he kept trying to sell me their services and I said I need to be transfered to a technician as you stated you would.  Well when I got on the phone.  I was on the phone for almost an hour and nothing got resolved.  They said they would have to transfer me to another department.  When I was on hold I had a co-worker hold the phone while I walked to deliver something to a VP.  When I walked back they didn't disconnect with my computer and someone went into my DOS program on my computer.  I kept trying to get control of my computer to disconnect them and the guy came on and he was denying someone was doing that!!  I was struggling and finally able to fight them for my mouse and disconnected them and ran a virus scan!!  HOW DARE THEY DO THAT!! I WOULD NEVER TRUST THEM ON ANY COMPUTER!!  DO NOT USE THEM!! Nothing I called them for warranted them to go to my DOS program!!
