I don't even want to give them a star

I don't even want to give them a star. Almost 2 years ago I open an account with them. If memory serve me correct I wasnt even 3 months with them. Then I was in an accident with my s****** and broke my leg and couldn't work. Until today I struggle to get work. Because I cannot stand long etc. Anyway. I canceled with them as I have no income and sold my s******. They kept on hassling me. And suddenly last weekend without my knowledge or permission they tried to deduct R500 from my bank account. Without success as I don't have money in my account. That is unacceptable and ********. 😡
