Agni Insurance Services Harassment Calling

 I was in an accident that happened in my sisters car however during that time of the accident it appeared that she did not have insurance but in fact she did her previous insurance was ending and she was switching insurance companies. My sister basically handled everything with her insurance company and they said they would not cover. Also I was not in fault of this accident ( this was back in Oct 2015 ) it is now March 2016 and this afni insurance services is still harassing me by sending letters and calls about me owing $15,000 something definitely did not sit right and I decided to do some research of my own and I discover similar situations and stories.Then they threatened to suspend my license so before when I was speaking to them explained I definitely do not have that amount of money and then after explaining they still was demanding me to pay, they was asking me if I could borrow money to pay $15,000 and just being very harsh. Again Something just is not right about this. I really do not know what to do but I have be doing some research and I will continue to file many more complaints about them. harassing, demanding, scamming and trying to use a scare tactic is not going to work. I need more answers and information so I will continue to research.
