Lost due to 500 internal server error - rating refund?

I lost 27 elo in rapid due to the worldwide server error. https://www.chess.com/game/live/146333881636

My opponent blundered right before the 500 internal server error.

There was an issue with the CDN the site uses. A lot of websites had issues

So can I get my rating refund? (I would have crossed 1300 rapid if I had drawn or won)

You could contact support directly to ask. Since it wasn't site specific caused issue there probably won't be any automatic refunds.

I contacted support via the menu, but a bot replied to me. Is my issue acknowledged by the support staff?

Why do they give 50% offers but don't let us try it out over the weekend? No staff, internal server errors, and diamond is now twice as much. How do they expect to get paying customers this way?

If the support tool did not say you would be contacted by staff, then no.

That's the always limited time offers work.

2 weekend days would be good limited time. You have a 48 window of time on Saturday and Sunday to try out the paid features. During the week, you will be working or going to school. The weekend gives you time to try it.
