AVAST Software s.r.o., Lisa Racz, Sandra Richard No proof of service provided and not eligible for refund...ripped off Charlotte North Carolina

There was an issue with a program on my computer. The Retailer Customer Support detected viruses, errors and other problems with our computer that may be impeding the program. They offered a clean/repair service. I requested a list of said viruses, errors and problems that warranted service. Was assured that one would be provided after service. We complied. Service was rendered through an online Technician. When complete, no summary was provided. We contacted Customer Service again to verify completion and obtain a summary. They said they only had a log of programs used for the clean/repair service. I repeated my request for a summary and list of errors. I was denied. I requested a refund. I was denied. The original program that prompted this issue still does not work. Our computer ran fine before the program and service and continues to work fine after. I simply want proof that said service was performed or a refund.
