Spice Jet Airlines — threatening and misbehave by cabin crew

Respected Sir/Mdm
Very disheartedly I m submtng few lines for Ur kind notice. Today I travelled IXZ to MAA FLIGHT NO SG 607. As my wife was having fever she asked blanket but crew told that since it's a low cost Arline they don't keep it. After few min crew came to me and requested to fasten seat belt that time I inquired her again and suggested to atleast keep a blanket and even told that I know it's not in there hands, matter was finished. In between all this I forgot to fasten seat belt few min later a male cabin crew came and jst started shouting at me ordering to put the belt not even once he told politely as I am his paid servant wen I told him he can't talk to me like tis his reply was he will and dont want passenger like me u jst think a while I was wit my family. Even he was moving his hands in front of me as if he may beat me I was threatened he was telling I misbehaved with his staffs which is totally wrong I don't know wt he wanted to prove at tht time. My fault was that I didn't fasten the seat belt for which he could have told me politely also. I asked his name but he denied and his name plate was also not there as if he came pre planned hiding his identity. I m a frequent flyer and today is the MOST WORST ex of my journey. Hereafter i have to thnk before boarding spice jet.
