I have an AIB MasterCard and they never supplied any info to the ICB. When I tried to get a loan from BOI they turned me down. I then got a loan from AIB, I think maybe that is why AIB don't report?
Do not phone/email depts as you'll have to explain your story over and over to different people, and when many hear ICB they will switch off, instead write a paper letter outlining the story, and concluding with what you want done, send it by regsitered post to BOI Card Services. If that fails move on to the Financial Regulator. Don't waste your time contacting MasterCard International, this is a daily matter with your bank and they do not handle those.
