I have received numerous calls from ( XXXX ) XXXX and ( XXXX ) XXXX, both of which belong to Creditors Collection Service. However, I only know that because I searched the numbers online. The calls to my phone either do no leave a message, or the message is a recording of a man leaving only the phone number ( XXXX ) XXXX. He does not say anything else in the message. I have records of nine calls since XXXX/XXXX/2016, but there were more before those.
