Need some help please

Ok I paid a company out of India to program my site, nuswag.com, and I didn't like the font choices so I asked them to change the fonts for me. I know the basics, and I mean basics of programing but I'm pretty sure all that has to be done is go into the CSS and change the font names, all I wanted was everything changed to arial. They said it would be a fee by hour at 20 dollars an hour and I was like ok, now they send me the bill and say it took them 24 hours. That can't be fisically possible right. I figured that would take 2 hours.

Although you've posted in the wrong forum really, and haven't really asked a question - after a quick look at your site it appears a quick 'find-n-replace' on your CSS would have sufficed.

Although you do have to take into account a minimum charge and testing...

Sorry about that, I wasn't sure where to post. My question is how many hours should it take. These guys had just built the site for me and I pay them to fix little problems etc. so there is no minimal costs just an hourly fee and I fell like they are just trying to scr*w me

Personally, maybe 2-3 hours including testing.
