Amazon India — toyshine fire station with three dolls

So i ordered this toy as a gift for someone. I got it on 20th october and was to gift at at a birthday party a few days later. By the time i found the problem it was 31st. The three dolls as described were missing, there was no instruction booklet for assembly, and some pieces for the assembly were missing. This product has other reviews with the same complaint which unfortunately i saw later. The seller in this case was sunshine gifting and it was an amazon fulfilled product. I had the option to write to the seller under the ‘contact seller’ option on the amazon website. I wrote to them complaint about the missing items. No one wrote back to me for almost a month. Then i pursued the complaint and called amazon customer service. I was told that because this was an amazon fulfilled item, the seller would not write back to me.in this case nor was amazon responsible for writing back to me. By then accepting that it was beyond the date to return the product, in fact even 31st was a day late, all i was expecting was an apology and some action regarding the product advertisement. But none of that happened. I was instead told that the customer service executive would fill a form on my behalf for the review team to look into. I could not get an acknowledgement of this as per amazon policy. I got the email for customer care and wrote them a mail explaining the issue with the product and asking for a response to my complaint placed on 31st october, reviews for the product and taking it down or changing the advertisement. The only response i got was a line ‘thank you for your feedback’ without even acknowledging that i had complained about the product on 31st october. I have since closed my amazon account. The customer service was terrible and i’m sure they don’t care of about one of their million customers and don’t mind losing one.
