Vsupport Llc Scam

I needed to phone Norton but had to use my smartphone to search for a phone number as my PC was not working.  I found what I thought was a Norton site and phoned.  It turned out this was a fake site.  I explained to the person who I thought worked for Norton what the problem was.  I fell for the usual scam story.  Trogan, can only be fixed by a third party company employing Microsoft engineers, free Norton for 8 years, need remote access, will cost $$$.  I paid and it was fixed but only for one day.  I realized after I put the phone down that Vsupport Llc are scammers and Norton confirmed this and have now fixed the problem.  I need further evidence for my bank that this is a scam.  Can people with knowledge of this please confirm as it must have been done many times before.
