PUTRID SERVICE!!!

My brother passed away in November 2014 and I put through a claim to Momentum on the 24th December 2014, to date I have received no service or feedback from this useless insurance company. I called the call centre in January 2015 and was told that the claim is still being assessed. I called the call centre again in February 2015 and was told that the claim is awaiting the trustees decision. I sent numerous e-mails pleading for a manager to call me or at least some feedback from them with regards to the claim and to date I havent even received the courtesy of an acknowledgement of my e-mail? This is a total lack of service from Momentum the worst insurance company EVER!!! I asked via e-mail if all documentation is in order and still no reply from Momentum, I called the call centre and asked if all documentation is in order and the agent Nolo Masana assured me everything was in order and that the claim is awaiting trustee resolution. I requested that the manager give me a calll and Nolo said that she will request for the manager to call me and to date I have not had a call from the manager and it has been two weeks now already!!!!!!?????
