Eureka Forbes / Aquaguard — AMC

i bought aquasure of eureka forbes from kolhapur bigg bazaar... i asked the aquaguard person to instal it, well he came after 8 days and installed it.. to my surprise this guy asked me for installation charges, me not being at home my wife gave him the installation charges. when asked for the annual maintainence he says that i[censored] buy these products from bigg bazaar u dnt get the AMC. this is the thing which ive heard for the first time.. and im going to give a writted complaint to bigg bazaar.
to people who dnt knw this better dnt buy electronic items from bigg bazaar be it anything. everyone thinks people are fools.. as no one cares to complaint...
