Claimed/Unclaimed Policies

I enquired with Liberty Life regarding the my late dad policies he had with them. The first time the person responded with policy information with incomplete policy numbers. From then we were given 4 days to resolve the matter but no response from them. I received 2 incomplete policy numbers policyholder yes it is the deceased but their service is extremely bad. I contacted them via emails,facebook,twitter but no solutions. I want to know all the policies he had with them,status,current values claimed or unclaimed Letter of executorship was sent already.
