This is a balls... really annoying !!! And I understand how you are annoyed too.

It will be very hard to get real "retribution" from these guys, that is just my experience.
If you are still feeling aggrieved tomorrow, go to your solicitor and ask them to draft a legal letter to the company. It should cost less than €100.
Maybe you will get some positive news... unlikely, but worth a try for €100 and your time / effort / mental health.

Otherwise, if it is going to take a lot more time and effort, and expense from your solicitor, I would probably veer toward just getting it fixed it.

My 2 cents. Best of luck.
