Air India - promised seat not given to us need refund

PNR no :- *JJH*V
we booked airline tct from easemytrip.com and paid in advance for costlier tct for comfort not to get trouble .

when in etct i m getting already confirmed seats **a and **b . airline was fully aware of one person is senior citizen becos before i selected **a and **b and when in email i received **a i called helpline they told me my mother is senior citizen so front row seat not given.
when i m getting on etct booked on * june airline fully aware of passenger criteria how can they justify it now eligibility or non eligibly . Even while seating the support staff a lady also told us we will get refund. it will be non refusable if i would have given **a and **a seats . last moment we got free seats like other passengers we stood in line . why we dont have any information about changing the seats ???? pls look again the whole scenario they are selling same seats many times ... when seat no is mentioned on etct its a negligence of reservation counter staff she didnt look properly and without information changed our seats....its a cheating and manipulation , my mistake is i trusted and paid in advance and even i trusted their words and agreed to sit on **c and **b... plsss plsss just over look the these are free seats allotted randomly , if i m not given the services **a and **b is the stilted seats i paid for comfort not for listening bullshit of air india.... this is not case of eligibility or whatever airline wants to decide at the moment or not ... when i paying more money than other passengers i deserved that service if not givn the services i need my money back simple..... pls ask the airlines to pay of their negligence and manipulation . i already wasted my time its been ** days i am writing them daily and i hop justice from you .

Airline was fully aware of my mother is senior citizen we booked wheel chair also .

Why airline is justify eligibility after I am asking my refund ???

Points to overlook ..

Why passenger haven’t asked before choosing seats **a and **b is there any senior citizen.

Once I already paid I should have got call from airline of agent that I need to replace the seats.

They are doing anything to hide their mistakes,,, why I will pay for their ill literate staff and poor customer services .

I have full faith in our Indian law and as a common man I don’t have money to put lawsuit on airline
