Operations and procedures continuosly postponed

My Mother, aged 74, Bibi Madhi, has been waiting for over a year to have a stent inserted. Her first stay at the hospital was for over 3 months last year and after 2 angiograms she was given the run around by Doctors. After a year of waiting she got a date to have the procedure done in January. In all this time her condition has worsened from having 1 blocked artery, she now has 3. So instead of inserting a stent, she now needs a bypass. She's been in hospital for over a month now. Been prepped for surgery many times but never made it to have the procedure done. Doctors keep stalling and postponing. We are at our wits end. There disregard of what this does to a patient psychologically is disgusting and unprofessional. They are playing with the life of a human being. My Mother is not a specimen to be experimented on. The longer she stays there with no treatment the more despondent she becomes and she is also a diabetic. I would like those that have taken the oath to do right by my Mother and respect her enough to treat her. She is the most important part of our family. Don't play fast and loose with others lives just because you have the power to.
