www.tammanager.com - Illegal and pirated software sold online

I saw the site, spoke to mr Venkata Krishna and purchased two softwares to maintain accounts of school on internet. I paid the money to him by Paytm. He promised that he will give support and they are freelancers who prepared the software. After about a week now I received a mail from qdocs that they are the owners of the software and mr Venkata Krishna sold me a pirated copy of the software. My conversations with him are all recorded. I also have the mail from qdocs that they are taking legal action against him. His mobile no is ***** *****. His site is www.tammanager.com.
