Ignite Web Services review: The owner refuses to pay, because he has found out many mistakes in my work

I have worked for the company Ignite Web Services. I made the content for their website and they provided me all details what I needed to include. However, the company didn’t want to pay and announced that there were a lot of mistakes in my information and writings. I am sure that they lie to me, because I have done this job as they asked me to. I think that they have received what they want and don’t want to pay for the services.
