It is suprising that such a reputed Company of India has kept unscupulous and underworld connected Dealers, in many parts of the country who when contacted about service or warranty matters, laugh at you and threaten you. They charge money without doing any service like oil or filter change. One feels scared that they will beat you up if you request them for any assistance.
Solution of your complaint
Kill these Tata dealers, not only Guinea Motors which must be the most notorious but most of others who also behave in the same manner if contacted for assistance. Liars and cheats.
