MS Network Support

In March 2020 my computer made strange noises and someone from MS Network Support Inc. said that they needed to check my computer for viruses. After a lot of time of watching this person take over my computer, I authorized the payment of $1799.99 thru my bank. They now call me every month to check the computer.
Yesterday I received a call from World Line Solutions Inc. telling me that MS Network was a scam so World Line took over my computer to clean up whatever they said was invading my space. For this service I authorized the payment of $2200 thru a credit card. How do I know which one of these companies is legit and how do I make a claim to get my money back from MS Network if they are not legit?

phone number came up while on the internet. It said my computer was compromised please call for help. So I did. They offered to put software on my computer. I let them. They asked for 2 payments of $250. I said okay. Three months later I received a voice mail from them stating that they would refund my money since they were no longer allowed to conduct business. I called them back, upon transferring the call to someone else, they hung up. After numerous attempts to call them, I did make contact. I was told I did not make payments, would I do so now. I was upset with this process so I told him just to cancel me out. The man, Ricky Gill, started on a tirade of how his boss was going to take my costs from him. He stated this was bad because he had children to feed. I said I had the same problem and was not interested in being connected to him. Then he stated that I was blackmailing him. I because upset and told him I was not. He hung up,
