Bad bad bad

Very bad communications. I requested that I don't have the vehicle anymore, I called and asked them to cancel my my subscription, instead what they did is they write me up for an huge amount. Without my concent they just took money from my account, twice In days this month, how can they do it? I'm the only bread winner in this family, so to take more than R1500 from my account and leave my family without food will be on your conscience, why cant the make any agreement? I think it's verby bad to just to me explain why I can't afford my familys needs this month,
