Free membership

You pay for any gift memberships. If you want to request refunds, you'll need to open a ticket with support.

The gifting process clearly shows it will pay with the card on file.

Ok. But I am still not sure chess.com will refund it. That will be So much work for me. It would really get off my mind if You guys could help. I did submit a "report" on how I want my money back. Please help!
Thanks,
Joshua

You are the only one that can do anything and a ticket requesting the refund for gift memberships is the only way to go about it.
You'll have to wait until support gets to your ticket.

According to their May report in https://www.chess.com/news/view/chess-com-month-in-review-may-2020, the average time to first response was 3 days and 14 hours: that's the average, and instances of up to 7 days hasn't been uncommon.

Worst case is that Chess.com loses track of your support request and we have to remind them again about it before they give you your refund. More likely is that they'll get to it some time before the 7 day mark.

Ok, this is really starting to bug me. I made a mistake, and I will lose like 99 dollars for a stupid mistake I made.

Ok but is it a possibility that I will have to suffer and pay for all of the memberships?
Of course "it's a possibility"... it's also a possibility that we might all catch COVID-19 and die (which, by the way, is very much worse than your "worst case" scenario above). You'll get the money back and will hopefully be the wiser for the experience.
As long as it's not involving buying a free premium membership which I was helping chess.com out in making a protest thread about the nonsensical terminology I saw in some other thread.
