Maruti Suzuki Alto
Changing of Stapny

I sent my Maruti Suzuki Alto in M.G. Motors Alwar for servicing in october after servicing i came back at my home and at home i see that my stapny was changed. my stapny whish was new but this stapny is old. I have very hurt that how can maruti do this? This is black spot on MARUTI SUZUKI. If Maruti dealers do this type with customers than what would be name in market of MARUTI.
