My aunt had a life policy, not much, but still and she paid it vigorously. She recently passed away and we did the necessary and obtained all the documents. It is now over 4 months and still we are battling with The Unlimited to get the policy settled and we have tried everything: Emails, phone calls, letters. They just ignore it and proceed with *****ing people's money and refuse to see to their responsibilities.
