Rak Ceramics India — multiple cracks on both western closet and its water tank

I had purchased a best quality western closet with its water tank of rak ceramics from melathil hardwares, thatta road, adoor on 12th november 2015. But 6 months ago i had observed some hair line cracks on both the closet and its water tank, but i didnt take it seriously. Now the cracks have developed further and the closet and its water tank have multiple clear visible cracks. Immediately a fortnight ago i informed to melathil hardwares from where i had purchased the product, who in turn lodged a complaint to rak ceramics and informed me that rak representative will come and inspect the product in 2 to 3 days. But nobody from rak ceramics has turned up so far nor contacted me. Considering seriousness of the matter please arrange for inspection of the closet by rak ceramics representative for replacement immediately.
