Tradus — Product is not delivered after online payment

Address:

Mumbai City, Maharashtra

My product didn't get delivered at all after online payment. I got messages and emails from them mentioning that product has been delivered. I informed them about the matter with getting a reply as whether I'll accept a gift voucher or not without any mention of the product I ordered.Then I got message saying issue has been resolved and requesting my buyer experience. Now they are contacting me over the phone and email accusing me that I have received the product but lying to them. Since I haven't recorded any telephonic conversation, I am attaching clicks of conversations via email.
