Eureka Forbes — Didn't get warranty card, service coupon and manual

Hi,

I have brought a Eureka Forbes water purifier 3 months before. And my customer ID is [protected].
They already installed the water purifier but they didn't provide the warranty card, service coupon and manual. I have many times in office and sales person (Harish[protected], they are not responding at all.
Even they didn't turn back after delivery of product. I don’t know what I can do for this?
Please let me know if you want any more info.
Thanks,
Subodh
