Paytm Mobile Solutions — return rejection

I had ordered armani analog watch my order number is [protected]. I was not satisfied with the product so i requested for return immediately after delivery. After 3 days i got a mail from paytm that my return request has been rejected with a reason that we tried to reach you but were unable to connect with you. My complaint is that the pick up boy didnt came to pick the packet and he didn't even contacted me through phone call or message. Its not my mistake. And now when i go to product detail page to return it again i am not able to see any option regarding return they have disabled it. I wrote it on the paytm resolve the issue page but there is no satisfactory response from them they said to send picture of product with model number and gave me helpline number but that too is not useful for me
Please resolve this issue i want to return the product
