LIBERTY LIFE POOR SERVICE AND UNSETTLED CLAIM

I have an outstanding claim to which I get absolutely NO RESPONSE from Liberty. Liberty did incorrectly amend details on the policy which meant that I did not receive any communication and in this time, I sincerely believed that the claim had been paid. However, last May, when I discovered it had not, I have had no reasonable explanation or response whatsoever other than to reinstate me as the Cedant. This is now EXTREMELY urgent. Please can someone advise how I "persuade" Liberty Life to actually investigate, make amends on the errors made at the time the claim was submitted in error by his then wife, Arlene Elcott, and finalise the claim. Policy Holder is my ex-Husband Raymond Terence Elcott ID *** 180. All details in this matter have been communicated to Mr Matthew Westphal (***) so many times I cant begin to say!!
