ICWS is making regular threats to many others in the most illegal form. They are not following the legal laws pertaining to debt collection procedure.
Use your federal rights and ask ICWS to send you the debt validation of this account in writing. You have the rights to refuse payment until you have been served with proper details.
ICWS won't be able to give you the required details because they don't have any such info. Cover your base by sending them a certified letter with return receipt requested. Once they have received this letter and fail to give the details, you have proof to defend yourself if the matter is taken to the court. But I am pretty confirmed that this company won't take the matter to the court because many complaints are already filed against them at the FTC, BBB as well as the state attorney general office.
You should also put your complaints at all the necessary places and force the bureaus to take strict actions against this company.
