PAYTM MALL Regarding wrong information in details of seller and cancellation of order on Paytm

Dear Sir,

I ordered a sony 43 inches led tv KLV-43W772E with the order number 3918925070 from brand seller shop, an authorized seller of sony as mentioned on the website of paytm. I have ordered the product as the seller was mention as an authorized seller for sony product. But, When I have checked with sony customer care, they told that the above mentioned seller is not the authorized seller. I mailed them regarding the issue and tried to call cuatomer care several times to Paytm and Paytm Mall regarding cancellation of my order as the product is not dispched yet for delivery. I tried to contact several times but did not get any response.
I request you to help me cancel my order at earliest as they have provided wrong information.
Anticipating your cooperation.

Regards,

Palak Parikh
