Extremely poor service

We have a rent to own contract with Planet42 for the past 3 months. To date the VW Passat has been in and out of a workshop from the dealer 2 weeks after we received the xar. On the 1st day the wiper blew off in stormy weather. The licensing we been told to pay and will be reimbursed. In short we are paying for a car we have only driven for a week, furthermore the car either stood still or been at the workshop. What is especially bad service you cannot speak to a physical person, you email Planet42 and no response after a week. You speak to the initiation agent and they even tell you they can get hold of Planet42 or ghey gavent responded to the agent. We sent 2 emails , 2 whatsapp messages and nit a single response. Our next step is to either cancel our contract, bt how does one do that when you cannot get hold of anyone. Please people out there, do NOT use this company as uts endless problems.
