Paytm — Got the product with missing parts

I ordered a lg tv 32 inch around 20 days back. After recieving the product i found that the adapter of tv is missing. I have filed multiple complaints on their toll free number and sent various emails for which i have all the records. After so much bothering paytm costumer care told me that the adapter is not the part of the tv. I called the lg service center and they confirmed that it is a part of the tv, as without adapter the tv won't work. This poor service is not expected from sauch a big online mnc. I want the adapter or the refund for the product.
