Imas ignoring customers

I have been trying to get hold of their reserve fund department as I sent in my policy cancelation documents weeks ago. I wanted to get feedback on the status of my cancelation and when the funds in my policy would be paid back to me. Nobody responds to my emails to which previous emails were answered from, their call center number just keeps ringing. Even when you ask for an operator, they put you through to this number that never gets answered. I am begining to suspect they count on me getting frustrated and letting go of the reserve funds that is owed to me. I hope I am wrong. If anyone from Imas reads this, please give me feedback asap, instead of ignoring my communications and acting suspicious.
