California Check Cashing review: Harrassing/abusive and rude 1

My son took a cash advance and used me as a reference. I have been having nothing
but harassing phone calls and conversation everyday 7x a day on my business #. I've
been told I need to come down and take care of his debt. I've explained my sons situation
and that I don't live anywhere near him. The caller then becomes abusive and continues
to call 5x more. I thought the normal debt collecting call could be know more then once a
day
