Received several calls from this company, but they did not leave a message. I called their number, and asked repeatedly what company they were calling from ; what they were calling me in regards to ; what was the name of their company. Their employees refused to answer my questions, instead they just put me on hold and transferred me to another person. Then they would hang up. I called back again, and finally one of their representatives told me the name of their company was Trans World Systems. They did NOT tell me that this was in reference to a debt. They asked for personal information ( my name, address ) but refused to tell me why. Finally, I told the person that I would be filing a complaint with the FTC if they ever called me again. I asked them to confirm that I had told them not to call me, and the person said yes. Many times during my call, I asked them what this was in reference to, and they refused to answer. The only reason I know that they are debt collectors is from Googling the name of their company. I have not been told what debt this is in reference to, so I can not make any judgment about whether it is an actual debt, or a complete scam. They totally ignored their government requirement to tell me that their phone calls were in reference to a debt. In addition, I believe that they are attempting to mislead consumers with their name. It would be easy to confuse their name ( Trans World Systems ) with the legitimate company XXXX XXXX.
