Tata Swach - Online Order - Damaged Goods Received — bulb problem

Address:

Karnataka

I had purchased a tata swach from Mangalore Karnataka. Within 1 months the bulb stopped working, showing accumulation of black water (the carbon filter must have leaked) resulting in chocking of the filter. We made a complaint to the dealer who refused to even take up the matter and instead directed me to call the tata consumer care cell on [protected]. Could someone please help.
It happning for me again and again. And none of the delaer in mangalore is having the bulb so that i can replace that also. Even "Tata Swath" online buy is also not working properly.
Please help me out.
