We blocked NCO Financial months ago, now they have another company calling on their behalf. The message is as follows: "Hello this is an important message from Trans World Systems Inc., a debt collection company. This is an attempt to collect a debt and any information obtained will be used for that purpose. Please return the call to Michelle Harris at 800-597-4549"--that number they tell you to call is NCO Financial. Trans World Systems Inc. shall be blocked too.
