budget insurance failed to fix my car

Good day

My name is Mante Nkadimeng I am writing to hello peter regarding my claim was rejected by budget insurance On the 25/07/2018 I had a car accident, a week later after submitting my claim I was told that they will not fix my car due to that I was unable to provide the necessary information to support the fact that I was previously insured without any claims or losses breaks or interruption. Before I bought my own car I used to drive my mother ‘s car I used it, to go to work with it ,which means that I drove it regularly more than my mother however the insurance that the car is covered under which is miway , was under her name because she is the owner of the car , when I took out the insurance with budget I did confirm that I never had any car insurance before or though I am regular driver hence is used to drive my mother ‘s car and my mother ‘ s insurance is an open policy everyone is allowed to drive the car as long as they are fit to drive the car and they have a valid driver’s license and my mother stays in Limpopo the car ‘s address is registered under the address that I am staying at not my mother ‘s address so I do not understand if they are saying I failed to provide evidence that I was the regular driver of the car and moreover the car is still at my address even now is that not proof enough that I am the one who used to drive this car and I even used the car to work. I think budget they are just opportunists that took advantage of a young black woman who is not knowledgeable enough about car insurances as this was my first car. they refunded me my money back for my premiums that I paid for 5 months which is 4628.25 and told me to fix the car myself and return their courtesy car on the 10/08/2018 which is sated on the contact that the car is valid for 30 days I was supposed to return it on the 24/08/2018 they are not abiding to their obligations Please help me get my car fixed and bring justice to this matter
