Godrej Interio — for not delivering full product

Bought two products on 12/11/2017 which delivered on 14/11/17, in the time of installation found lower drawer of design table cum wardrobe is missing and we informed it to sales executive by phone and she gave us an enterprise no, we called they told us to give that on 1st week of january but it still not come.. When we call madam she gave another no and so on.. Previous day before last day she gave a no name mr. Avijit after contact, he told on that day another call no is generated.. Again he gave us another phone no of service centre executive, after calling him yesterday he informed us a person will be sent today to inspect.. Today he told that product is not in stock so no one will come and they sent requirement of that product..
Sir can you provide me information when we will get that already more than two months over. We couldn't expect this type of harassment and non professional behaviour from a renowned company like godrej interio..
