I have written the book “Automata theory and compiler construction” in[protected] and book published in year 2021. Till date I have not received any royalty from publisher. In this book, first author was Dr. Narendra kumar but he is not provide any support for this issue and saying publisher is not picking the phone calls. So, I suffering from mental stress because I have written this book in 2 year and I get nothing and no information regarding this book. And book sell by Amazon and other website online. Please do something and provide compensation for this. I have all proof. Was this information helpful? |
