I have received phone calls from a person who would not identify themselves saying they were with a company called Trans World Systems. All they would disclose was that this was about a personal business matter. I asked them three times what it was in reference to and they said they would disclose that later on. I responded if you do not disclose what this is about then I will hang up, they would not so I hung up. The phone calls came on XXXX/XXXX/2015 at XXXX two days after I had XXXX which impeded my recovery. The other call came on XXXX/XXXX/2015 at XXXX. This company has an address of XXXX XXXX XXXX in XXXX, TX XXXX. The number that they call from is XXXX is not even a registered number. The XXXX that is given to them XXXX is registered to a XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX, Tx XXXX. The other number XXXX is actually registered to the company.
