I got a lot of calls from this number and the caller were pushy and rude. They asked me to pay them money directly and immediately for a dental service I got from my local Castle Dental that I had paid before I got the service. They said that because the insurance company denied the payment. I told the caller that I need some time to invest the case. But the caller insisted getting the money immediately even though I have'n gotten any written bill. This company only takes care of money, They don't hear you.
