Hindustan Lever - Pure It — Customer Service

The Customer Service offered by them is absolutely pathetic. I bought this piece of about 2 months back and the sales guy called me about 23 times to sell this to me. After delivering the product he said he will come with the invoice in 10 days and check if all is fine. Since then he rejects my calls and customer service keeps forwarding my complaint to someone (I don't know who this self-proclaimed GOD is) and my invoice is still nopt delivered.
PATHETIC SERVICE - DO NOT BUY THIS JUNK.
