Weso Infotech Breach of Contract Chennai

I had signed a contract with the company WESO Infotech from Chennai, India, who is now in breach of same. I offered originally $2,000 to have a website built and they bid $ 1,800. They offered me a life fixing bugs guarantee, which is in the written contract. That made me choose them, and to motivate them I offered to accept to pay them $2,000 which was $200 more than what they asked. They of course accepted. Furthermore, I paid them an additional $500 for adding some options to the website.  

They have now reneged to fix bugs which have developed in the website and are ignoring me. Whoever thinks in doing business with WESO, needs to take into consideration their lack of seriousness, and the fact that they do not respect the terms of a written contract, and as the evidence shows, they will offer anything, even in writing, to win a business.   This is a clear-cut case of breach of contract. When I say the evidence, I mean the written contract which they are not fulfilling. I dealt with Mr Antony Dinesh Dawson, Chandler and Charles Asir   They are on Facebook, upwork.com  Freelancer.com   Guru.com and other.
