Today 06/ Oct 2021 round 11:21am I received a call from lady she gave me info regarding the call saying that I have outstanding bill I asked who handed me over and that it must be last call she made to me no one contact me previously regarding medical bills, and she said that matter of fact I own I told her its not mater of fact that I own no one called me previously and unfortunately I will not be reliable for attorney fees. She stirred me up I was rude and drop the call she had nerve to call me back telling me that am a low life and mst not use private hospitals and rather go to Bara and she drop. I called back asked for manager spoke to Cheronise Davids but it actually sounded like same lady so i told Cheronise about the agent that sad am a low life and her respond was yes but you must pay told her its not about paying its about how agent address me and she told me she wont get call recording but rather report me to our HR I told her than she more than welcome to do so we can take it from there, this so called manager dot have clue how to manage or speak to people where is her people skills work ethics and integrity. I drop call on her as well and she send me threatening sms
