Tate & Kirlin Associates, inc. Unrecognized debt Philadelphia Pennsylvania

On March 26 I had received a letter from Tate & Kirlin associates inc. stating that I owe $139.97, the creditor labeled TRS LIMITED I have no prior knowledge of owing that particular amount for anything as well as ever hearing of TRS LIMITED or Tate & Kirlin. I have done some web searches of Tate & Kirlin and it turned out that some one else had also received a similar letter via mail stating that they owed the exact same amount and that their letter was also received on the exact same day with the exact same letterhead dated March 20 2017 as well. I find this to be too much of a coincidence to be a legitimate mail. If however it turns out to be valid I will gladly accept to pay this, Strangely enough I have been calling all the numbers listed and not once did I get to speak with anyone.(it kept telling me to wait for next available representatives) Any help with this issue is greatly appreciated
