Not meeting customers requirements, due to their negligence

I had been in an accident. My policy makes provision for a loan vehicle, which I received on the 11th October 2017. Budget took 3.5 weeks to approve my claim. This left me with only a couple of days left to drive the lian vehicle. I contacted them a couple of times, whereby they extended it for 5 days, however, the panelbeaters only received the vehicle beginning of November 2017, which is unacceptable.

When I asked for the first extension of the loan vehicle, the lady confirmed via phone, if my car has not been repaired, they will extend it further. However, Budget refuse to be of any assistance. This is causing me to have a lack of income, as I am in sales. Who will cover my costs?

I will cancel my policy with Budget, due to their bad service.
