Indian Railway Catering & Tourism Corporation [IRCTC] — Regarding its Services

Dear Sir

I have a complaint against the service of IRCTC, that it is not providing the services properly. Day before yesterday during the reservation I had requested the side lower sit and then I got the sit No. 32 in S4
but today I saw that the sit No. 31 was side lower and 32 was the side upper.
what is this ? Am I not paying for the same? or anything else. it not acceptable.
I will complaint for the same to the higher authority.
