Indian Railways — complaint regarding seat allotment

Address:

S M Road, 55/2285, Mumbai City, Maharashtra, 400037

My pnr - [protected]. I booked the ticket after availing concession for senior citizen. When i got the ticket i found that seat allotted to senior citizen is upper birth. It's neither lower nor middle. Is it right to allot upper birth to senior citizen specially lady, if not then kindly make it right. When i contacted to irctc for this then they replied to book the ticket in senior citizen category and in that category no seat available for this date. My date of journey is 23/02/2019.
