Swiss Telecom Carrier, Swiss TC and STC.

Swiss TC ( Munder Mahdi and Ahmad Mahdi ) owes Prolinks 19234.00 USD and are refusing to pay.
They do not reply to our e-mails nor to our telephone calls.
We would appreciate if any company dealing with them can help us (michel (at) prolinkslb.com) offset this amount.
Thank you.
