Hi Ashok, I'm Adv. Niharika and here is my take on your query.
This is a case of breach of contract. So, every document that you have with you which indicated your contract with that company, like transaction details and a copy of communication regarding the website development will support the cause of your case. You can seek damag under sec. 73 and 74 of Indian Contract Act, 1872.
You can set the crriminal law in motio by filing a FIR at the local police station under sec. 420 of IPC, 1862 for cheating.
Other remidies are filig a complaint at District Consumer Redressal Forum.
Fourthly, you can also file an application before the Permanent Lok Adaalat in your city/district.
I would like you to know that for filing a complaint before the District Consumer Redressal Forum and Permanent Lok Adaalat, you don't need to engage a lawyer, you can present your case by appearing yourself and bringing the documents and facts on affidavit.
I hope this resolves your query, for further information you can contact me at niharikalohan@yahoo.com
