Bookings not Disabled friendly!!!!!

Hi Computicket. Thank you for making the booking of disabled tickets so extremely impossible. Andrea Bocelli tickets went on sale Friday and we could not book online instead we were directed to enter a form or call the customer care line. I entered the form and your lines were down. I then went to Checkers early morning to see if I could book directly there, the lovely ladies at checkers called you and someone took down my details (name , number , email ) and advised me that they have reserved four tickets (2 disabled , 2 assistants) and that someone will call me when its time to collect the tickets and pay. Monday came around and I hadn't received a call yet so I called your customer care line and the lady that assisted me advised that you have my details and someone would call me within the week I shouldn't worry. It is now Thursday so I called you guys again only to be told my tickets are not listed down on the system and that disabled tickets are now sold out and I should go back to checkers which I did. Again , your staff advised there is nothing they can do , despite the fact that I have given you my details for bookings on 3 separate occasions , and that should additional tickets become available , I will be contacted for bookings, which clearly worked out so magical the first time , I should trust it will work again. Thank you for making my 87 year old Grandmothers dream of seeing her favorite artist completely out of reach. Your service is shocking and if you cannot handle the admin it takes to effectively book disabled tickets then maybe you shouldn't offer them in the first place
