Request for Credit Refund to Submit Course Workbook

Hi apologies for the question but seem i accidentally burned all my credits by click run on an entire table...(learning). and I can't submit the course workbook, as I can't run the claygent prompt (requiring credits). Would it be possible to get a little credit cash back so I can submit the assignment? I turned off auto updates in the columns, so I guess that's what triggered it. Tx
