Ticketmaster complaint: Refused accessibility ticket

I bought 2 for queen Adam lambert at the time I applied for,an accessibility ticket too . I filled in all details and sent them the proof the asked for and waited. When my tickets arrive in my account I checked my tickets only 2 full paid in my account I emailed them they asked for my details and proof again cos they couldn’t find it. I sent the ation email to them. Then the person said no problem here is your access code too use when I order tickets in future and an accessibility ticket will be added to this concert and any future events I thought excellent it showed up on my eagles ticket but not the queen 1 so I email and they kept ignoring my request about 5 emails later I got an answer. IM SORRY BUT YOUR ARE NOT ELIGIBLE FOR ACCESSIBLE TICKET COS YOU NEVER TICKED TERMS AND CONDITIONS. I thought what you must be joking .I tried complaining but kept ignoring me .I have tried to find away to complain to their management but no success. Their answer was not their problem and I couldn’t even get a refund from them this is a disappointment and a disgrace how they can get away with treating people like that .The concert is on 2nd June. I have had no alternative but to sell my tickets. To which I’m so upset and so angry I can’t even get a proper response from ticket master I am disabled and need someone with me constantly.im so upset there is no one I can scream at.
