Hello sir, my name is amin, i booked ticket with spice jet for ahmedabad to hyderabad, i am from a small village and due to my slip disc injury that is l5-s1 with lots of damage i am undergoing with treatment called pysiothreapy in my town. I booked my ticket during my treatment and right now situation is my doctor said that you need some more time then only you able to travel. My booking was for 1st september so i call customer care for asking change as my doctor told me, so spice jet first ask me for proper documents submission and i done with procedure after waiting for three days for spice jet reply, they clearly say no for my request without any reason, whole day with my bad health i contacting spice jet, every 3 hours i was calling them and sended lots of email for my requested issue. They not agree for changing my travel date and at last i ask please do cancel my ticket because of medical reason and refund my money they again replied me with no reason that we not refund your money.. I am so disappointed that in the medical case they are so rude and no customer feelings, they even don't know what is my injury. I can't able to walk 50 feet can't stand so my doctor was asking for more treatment to make me cure.. I just want to complain to a consumer complaints department that please this is my genuine problem and they done this with me.. I am very middle cast family and with lots of medical expense, i was just willing to waive off charges they make for changes, in my tickets but they say clearly no, i don't understand why then they ask for medical documents if they dont allow. Below i am attaching my documents picture and also my tickets picture. Please help me.
