Car hire can't be extended because option not chos

can't express the way I am stressed, depressed and confused with the less information explained to me when I took my policy,I am new car insurance client but I do pay attention to detail alots,I logged a claim on the 27/12/2015 that is not yet finalised ,due to time passing and careset car days about to be due in 10 days ,I had to ask claims administrator about extending car hire to 60 days,only that time I was told that option needs to be added when you have no claim at an extra cost and this is all new to me and someone who is based in rural area with no public transport to take me to work,how will I go if this was explained properly to me I wouldn't risk by not taking it,i have to go to work everyday in the morning now since I had to return back Avis car what should I do because it neither my fault discovery consultant didn't explain all terms of this car hire option to me and now I have to suffer for something that should be explained properly to me.since my DQ was not installed due to unavailabilits of people in my remote area but I am paying for it ,how will I survive without a car in such rural environment with no transport you guys failing to service your client too?
