YAM Racing, Selangor, Malaysia ..they refuse to pay

They asked me to work as a Media Exec, a racing team called YAM Racing, for the Merdeka Millenium 12-Hour Endurance Race. At first I was asked to write a press release, that they will be participating in the race.

I asked for a fee of USD$80 but the Director, Faizal Hakimi Jaafar said money was not the problem. After that, they asked me to do some photography work, attend the qualifying though it wasn't in the description. For my extra work, I am claiming a total of USD$95.

Now, they refuse to pay saying I didn't do my work properly and I didn't do this and that. I had asked them if there was anything else they wanted me to do, they said "NO" and thus, I didn't attend race day. He has even gone to the extent of not answering my calls.
