Worst company ever!

Never ever again! Its the worst company i have ever had to deal with. I had a unit and my car was written off. They made me to pay to de and reinstall then had to pay to do a contract for the new owner. We were at the end of our agreement and all payments been made then they decide to take money out my account its been 2 months and numourous phone calls without any help, managers, and agents are rude, everytime i call my query is at step one Absolutely disgusting service.
