angie's list holds business owners hostage Internet

I am a business owner who has excellent reviews on Angies list.   I have been a member since 2012.   Last year we serviced a customer who is very mentally unstable.  She started leaving reviews for my business over a course of a year.  Each time I filed a rebuttal with copies of her emails her story would change and get bigger and bigger.  

Stories such as-   I  never received a contract.  I sent her a copy of her contract and her statement "Where do I sign" email which was 4 weeks prior to her service.  

Next she had to reschedule and was not ready for my service because her father died.   I posted her facebook page to which it stated her father died 9 months prior to her service. She then changed her story and said she was preparing her fathers house for a sale.  I again posted her facebook to which it showed her vacationing in Albany and also her email stating she had to reschedule do to her vacation. 

The list goes on and on.  While searching Angies list for something else I found her review she left last year and responded to it.  I also stated I was sick of her lies and was turning this over to my attorney for a lawsuit.   I was then contacted by a very rude Kyle Mathes Integrity person from Angies List who informed me that if I sue her or take these issues to my attorney Angies list would drop me from their search. I offered to show my evidence and the insanity and slander that I have been dealing with and he refused.   Angies list is holding business owners hostage.   They have no right to tell me I cannot sue a person that is effecting my business montarily by a lying mentally insane woman.  Sure I filed my rebuttal by why should I have a negative review on my business that is not true. 

Angies list is a scam.  All they care about is collecting their 10.00 a year from people.   Rest assure the next time they call me to advertise at 300.00 a month I will be hanging up on them.
