They won their judgement,they filed for garshiments but was turn down because SC doesn't do garshiments. Then they went to the county I work in Ga to file for garshiments they were turned down again. Now they have filed for a judgement using my work address and won, so I received a letter to my employer to start taking out of my check. IS this legal, can they do that? What can I do to stop I have 45 days

So did you appear in court when they sued you in GA? When you bought up jurisdiction in court, what was said.

There was no court date, the judge just signed and then a letter was sent to my work and home telling the payroll to start deducting from my check. How do I fight this?

You said they filed in GA and "won"

To get a judgement in GA, they had to have had a court hearing, they can not just file and have the judge sign, unless you were notified and there was a hearing.

Oh yes they can! We were served with papers from a credit card company that they had filed suit in Superior Court here in Georgia. We answered. They asked the judge for judgement - no hearing, no court - and the judge gave it to them based on the fact that we did not deny the debt.
