Planet42 Poor services

I'm renting a car from Planet42 from March till now I only drove the car for 2 weeks. Firstly I broke it took them 3 months to fix I drove it for 2 weeks its broken again. Now it's the third week waiting for it to be repaired. In the first instance Planet42 and dealer delayed the payment. Now the dealer is delaying the payment he **** money will reflect on Friday that never happened Monday he was not answering his phone. I asked them several times to release me from this contract as it s unfair and abusive. I'm using a taxi but I'm paying rent on the other side. I think Planet42 and the dealer must take responsibility for failing to adhere to the terms of the contract.
