Sintex Industries — New sintex tank problem

Dear Sir

I purchased one 1000 lit. sump and 500 lit white Sintex tanks and installed the same on 13th of this month. In the black sump tank the top lit was found broken and the same has been returned to the dealer (Joshi & Joshi of Trichy, TamilNadu) for replacement.
This matter has been informed to your Sales Executive of Trichy area Mr. Veeramalai and he has assured to replace the same.
But I could receive no lid so far. So kindly arrange for the replacement immediately. The tank is in open condition. Pl. help me Sir.
With regards
R. Ganesan
