Instacom Ltd UK

Hello Voip Partners,
can someone help us to recover (offset) our payment of amount USD 3388.00 from Instacom Ltd UK. Since we are chasing them approximately since one year. They got every time excuses of changing management as well if they offer any route that work only for 2 hours with hardly 3-4 ports only.
If someone can help us to offset kindly let us know. Further to that if Instacom Ltd UK still unable to offset then we will release an alert to all VoIP community, so our other partners would not affect such kind of company.
