[Resolved]  Acer / Computer City, Asansol — justice against fraud

I m a physically handicapped person, purchased "acer" computer from the Asansol Book Fair ground in January 2007 (from dealer named Computer City, Asansol), in installment from Bajaj Finance and paid all installment in time, but despite of lapse of more than 9 months the did not give me either purchase receipt or warranty papers. In addition to this in the month of Nov'07 i requested them to improve my RAM from 128 MB to 512 MB, for which they charged Rs.1400/- . But recently, when despite of repeated request they did not send their soft were engineer for correcting my computer, i had to hire another soft were engineer, who find that the Computer City has added RAM of 256 MB with my original RAM of 128 MB. Since then i had tried contact the soft were engineer several times but could not succeed. As the Computer City, Asansol has cheated me, i m very much depressed. Also, as the show room is on 1st floor, i can't go there being handicapped person. So, i need your help fo9r justice and compensation at an early date.
