Pathetic service from budget ****mers

I rented a car at Budget avis car rental using flexiclub but I didn't like the car 10minutes after collecting it but I was told that I cannot return the car because there is no refund for unused days since I rented it for a month, I then went to change the car but I was given a faulty car with breaks failing and loss of power while driving up the hill but still I was told that I cannot cancel the contract, so I stayed with the car till today and I decided to return it even if I won't get my refund it's owk, I took the car to avis grand central airport midrand, i don't care if I get my refund or not but I will never ever rent anything from budget, full of empty promises and lies to **** people.
