Rashida Harianawala review: a staff of airasia flight xt852 on 27th october

A lady staff of AirAsia flight XT852 arriving from Bali to Mumbai on 27th October. I and my husband we are senior citizens were allotted seat nos 17F and 17G a fellow passenger on the next seat I suppose as 17E was very weird dirty &stinking so badly I was getting nausea still I tolerated but was not a good person continuously pushing his elbow from the sides pretending he was falling a sleep every now and then, in between would watch dirty films it was disgusting.I was helpless my husband could not sit in the centre seat as he had a right leg knee problem, therefore there was an empty seat on the ahead row I think was 17 C so I went and sat there but the staff lady said that was a hot seat and I cannot sit there I went back to my seat and tolerated this nuisance till this person got off at KL I was releaved to my surprise this staff was aware she could observe this weird person I would like to get an answer what can you do about the hot seat when once the fight has taken off in my case from Bali then also from KL and the seats are empty I understand if the seat in the upper class are empty I cannot go and upgrade myself but just a row ahead pls kindly look into this matter thank you
