Agency Not Paying Up Advice Needed

[gtullett]

Hi,
I have a problem with an agency not paying.

I decided to quit a contract a few weeks ago and rather than let me work my notice they agreed to pay me the four weeks, so i left the contract.

Now whenever i try speak to the agency about this i am ignored.

Have had no money and am a month out of pocket.

Not sure what to do next.

Any advice appreciated

Gerry
