Process for getting a slab label fixed by TPG

I didn’t realize when I bought this coin last year at a Heritage Auction that the PCGS label said Large 0 but the auction site listed it as a small 0. It is indeed a Small 0. So what process do I need to do to get this corrected by PCGS?

If it is a mechanical error, call up PCGS customer service. In the past they have fixed a couple for me for free but might take a couple months.
If you go to a larger coin show where PCGS is set up, you can give it to them there. They'll either fix it at the show if they're doing on-site grading or take it back to their office and then mail it back to you after they fix it.
Worry is the interest you pay on a debt you may not owe.

They will fix their error free however, unless it matters greatly, I'd keep it as is as a novelty. Are the values similar?
Small 0 is $850 vs Large 0 at $650
That should be an easy fix. Call customer service and they will give you instructions. Cheers, RickO
