I sense that MikeJ is calling you out on taking responsibility of your making two, not one, errors in improperly filling out the bonus code information. I haven't done a promo there for a while, but the instructions are pretty explicit regarding filling the correct information, iirc.

Now, assuming you are/were successfully tracked with PSO with the poker room in question, I can't really see a reason they cannot credit you with the PSO points.

The simple thing to do would be to take your business elsewhere.
