Multiple calls when due for a payment up to 7 times per day. More recently they called my father 6 times in 2 days between XXXX/XXXX/15 and XXXX/XXXX/15 concerning a payment that is not due until XXXX/XXXX/15. They did not call me at all. My father called me and relayed the message to me. When I called them at XXXX the rep was confused and said " uuum I think this was a courtesy call ''. He confirmed the due date was XXXX/XXXX/15 but could n't give a definitive explanation for the calls.
