I 've received 4 collection calls from this number, XXXX, of which each time a automated message is left on my answer machine. The caller ID says " XXXX Service ''. The four dates I received these calls are ... XXXX/XXXX/XXXX at XXXX, XXXX/XXXX/XXXX at XXXX, XXXX/XXXX/XXXX at XXXX, and XXXX/XXXX/XXXX at XXXX. 
I also know that calling times can not be earlier than XXXX.
