Can I get my money back from my Clipper card?

Excuse me, I was wondering if you could help me with a question regarding my Clipper card. I recently made a transaction on it, but I'm now reconsidering and wondering if there's any way I can get my money back. I've looked online but couldn't find a clear answer, so I thought I'd ask here. Is it possible to get a refund for a transaction made on a Clipper card, and if so, what's the process for doing so? I appreciate any information you can provide.
