Passing the buck, disgusted

On the 26th of April, I returned to DBN on the 12:45 flight from ORT. One of my bags wheels was broken off and another part was broken off. I contacted BA on the same day to report it and was told that I needed to deal with COMAIR directly. What is the purpose of having a complaints link on your website only to refer you to another company. I then emailed COMAIR as per the email address on their website and that bounced back. CAN SOMEBODY PLEASE ASSIST TO RESOLVE MY DAMAGED BAGGAGE CLAIM.
