No Service and No Refund

There are three companies, Restoro, Paddle and SafeCharge...Buyer beware! I am a senior citizen (75 years old). I paid $544.73 for a Restoro service to assist me with my software when I had trouble. That service was abruptly canceled for no reason. They refuse to refund my $544.73. I was also supposed to get MacAfee and Cyber Ghost, which I also never got. I was defrauded, misled and duped. They they took advantage of disabled old man. Do not trust these companies. All I want is my money back, because I never received the services.
