Instafixus review: Online computer repair and security software

Instafixus called me saying I had several problems with my computer and only Instafixus program could offer support to clean all security issues from my computer. I had used Norton for years. They told me Norton didn't make a security program for Windows 11. I paid 499.99 for a 3 year plan then discovered Norton does offer a security program for Windows 11. I would have researched before buying. However, there was a technician from my internet company here and he told me I needed to buy the Instafixus program. Is there anything I can do to get my money back?
