Rental Extention a real mission to get

<p>I was involved in a car accident on the 21 of June and claim was only authorised on the 10th of july. Ive been calling discovery since last week Wednesday to request an extention as i nolonger have rental days. Now i am receiving calls from avis requesting i retun the vehicle. while in the meantime my vehicle isnt ready for collection. I really dont expect such from Discovery. Can someone sort this out ASAP. </p>
