Eureka Forbes — Company not providing Warranty/Guarantee card

Recently two months ago I bought Eureka Forbes Aqua Total RO and the company executive assured that I will receive this document within 15 days by corrier. when I called up after 15 days the call centre person said it would take 30 days.. even then I did not receive.. after 30 days whwn I called up the call centre person increased the duration by 45 days.. now they are telling 2 months. Till now the company has not sent the Guarantee card. The sales executive who delivered when contacted talks as if doesn't know any thing about the product.
The funniest part is that the call centre people do not even ask for Reciept no nor Address other than name and tell that I will be recieving this document within few days..
I really don't know how they can send a document by asking for a name.
I am really confused, if there are 10 customers by my name ( for example) and If I ask for a Guarantee card, will the company send this Guarantee to all, because the only thing they ask is name and immediately tell they will send this document.
