@Cryxel In that case I would contact the helpdesk again, leaving out all of the extraneous information and focussing solely on that. The way you've presented the issue on here does make it a little hard to filter out the relevant information.

If you simply say "Before donating my UL was X, but after donating my UL still showed X, not X+Y. Please can you investigate? Thank you" then I think it should be clearer.
