Don't expect any customer service from Planet42 or the dealerships they are contracted with

I have entered into an agreement with Planet42 regarding a vehicle, which was mostly broken down from day 1, the car was more at the dealership for repairs as I have had it. It is now more than a year and on their website it states that I can return the vehicle after 6 months and if there are no arrears, my account is up to date also by paying a penalty of 1 month's installment. I have informed Planet42 that I want to return the vehicle on email and whatsapp and was asked what is the reason that I want to return the vehicle and I stated that I no longer want the vehicle. Since then I am being ignored, all email, all whatsapp messages have been ignored. I cannot make any contact with them. I have also informed the dealership Optimal Auto in Boksburg of my intention to return the vehicle which all my emails have gone unanswered. It is the worse service I have ever experienced. Please be advised never to enter into a contract with Planet42,! Beginning of June I will return the vehicle to Optimal Auto and then Planet42 and Optimal Auto in Boksburg will have to see what they are going to do.
