extremely slow and bad service

I have submitted info for Liberty for a claim on my fathers policy in Feb Then middle of march they ask for the same info again I send that info again after that I phone them weekly and get he same response from the call center it is with the trustee they will sit this week then the week pass then I phone again then I get the same results from the call Center the trustees will sit this week so it keeps going on. Very very slow and unhelpful service.
