How do I contact the Ringcentral fraud department I want to port out my Ringcentral phone number

  Ive been trying for a week to port my Ringcentral phone number to a different carrier and they have been blocking my carrier and myself from completing the transfer. The carrier has made several requests and also called Ringcentral 3 times this has been going on for a week. I have called RingCentral many times and spoken with people in many departments including the porting team and no one seems to be able to help me.

Then it was discovered when Ringcentral declined the port they then closed my account and so now no one can help me port the number. When I tried to reactivate my account they refused and said it had been locked by the fraud department but there is  no reason why and I was told there was no way to contact the fraud department except by email and they do not seem to respond to emails.  I called and asked to talk to a administrator at Ringcentral and I was told this is not possible. 

Does anyone know a phone number for the fraud department? Ringcentral provides information on the website on reporting fraud but the phone number posted is disconnected there doesn't seem to be a valid way to report fraud at the Ringcentral website

I feel like Ringcentral is devoting all of their time and resources to stop me from porting out my phone number and if I understand correctly they are required to do this by the FCC and they say they will port out ringcentral phone numbers on their website 

Can anyone help me?

Thank you
