Poor service

Instituted a 3rd party claim for an accident in March. Every time I contact Mutual and Federal some authorization was not done or documentation is missing or it is month end or some other dull story. I do not have full use of my vehicle and everytime the claim gets escalated to some department but only after I phone them. After a month of promises the payment is still not made and is AGAIN escalated to the payment department. Very very upset and unhappy with the service, don't want to recommend anybody to Mutual and Federal. <br> <br> How long should one wait and be patient and be nice?
