AVIS FLEET MANAGEMENT NOT RESPONDING IN-TIME

Avis as the fleet management company handling the payment of my vehicle theft claim are not paying out in the time given as per agreed. AVIS supply a courtesey vehicle for 1 month according to the Insurance company, Willis. I am without a vehicle now for 4 days after my claim is now in review for almost 6 week, I now have to arrange transport with other people to get to my work place and back everyday. Everyday the person handling my claim is having excuses of the financial manager not responding or the finance department taking their time to load my account on their system etc etc..
