On XX/XX/XXXX I suffered a XXXX. it was so severe that I past out. My wife called the City of XXXX XXXX Fire Dept and, still XXXX I was transfered to XXXX XXXX City Hospital. The amulance Services charged my insurance, XXXX primary and XXXX XXXX, secondary the amoun t of {$1400.00}. For unexplained reasons XXXX denied payment. XXXX XXXX paid {$1000.00}. I was never billed for the remaining balance till last XXXX XXXX when I received a letter from Harris & Harris, a collection agency, charging me {$500.00}. On XXXX XXXX I contacted City of XXXX ambulance services. They accepted that they had not billed me at my right address and a lady by the name XXXX assured me that her office " would pull out '' the charges from Harris & Harris and would check the status of my account since my secondary had already paid most of the charges and more than 2 years had already past. However, I am still receiving calls from Harris & Harris, even on Sunday mornings, when they call me at around XXXX Pacific time. They have called me at night, well after XXXX playing a recorded message demanding payment of the debt. On XX/XX/XXXX I called Harris and spoke with a gentleman named XXXX who apologized for the inconvenience and, again, assured m that they will withdraw the charges since his records showed that XXXX XXXX had paid a portion a XXXX, according to him, had made a payment on the account. Still, I keep on receiving the pre-recorded messages. On XXXX XXXX at XXXX I received yet another call despite all the promises of pulling out those charges for which the XXXX Ambulances Services has already been paid for.
