Jaquar Bathroom Fittings — No action taken in manufacturing defect

I bought a wash basin from jaguar outlet in which there are internal cracks, if we touch the surface it's smooth but cracks are visible. I made complaint at the customer care many times but no action is taken. First complaint was made on29/5/15 ...then again on 8/10/14 both time a person came and said that there will be a senior visit but no such was done... It's been a year and no action is taken ...now can I expect a requisite action to be done as Asap.
