Poor client support and false statements

I cancelled my contract and I was told I had to pay one month penalty fee. I delivered the car back and then was told I had to pay another month penalty fee!!! After a lot of deliberation I eventually decided to pay and Planet42 offer me a payment plan. The word they offer me. Then Planet42 called to informed me that they cannot do a payment plan and is going to take the full amount. Planen42 is not clear or transparent and blame it all on the customer. !!!
