Philips India — mixer grinder,I am complaining against service team of philips

Hi
I am mrs anjana laxman kalyankasture. I jave bought a mixer grinder, model no.-hl7756/00. Fo rs.2849. I have bought this mixer only due to philps brand. I was very trust on philips.
There r many fault in this well designed, mixer, i have tried. Much times to show these faults to their technitian, their local technitian wants to earn money by giving us each gasket for rs100. Even my product is in warranty. He has himself done practical and result was in front of him. That all buttermilk was spilling and spreading throgh lid of liquid jar and tomato puree through small jar. After that also he was advising me don't do buttermilk in liquif jar, u have to do only idli atta, in that jar. And buyblender for buttermilk.
Again after complaining oher technitian has come he has given me new lids but after that also lids vibrates and liquid and tomato puree spills through the jar. Again i complained but their technitian is saying that our product is like that only we can't do abything but my question is that ur brand is no.1 brand. I have bought ur mixer only due to brand name, it is not a local product, i have again complained before seven days but uptill now reply has not come.
So pls help me, to refund money i don't want to live with philis for much time.
Again this mixer has many faults
1. Jar becomec hot within 5-10 minutes in processing evev if philips has written that mixer can grind continuous 25 minute
Pls reply as early as possibl. I am much tired to their team
