negligent and exploitative company

i sold my car after a year abd informed Beame Customer Care by email a month in advance. They decided to respond after 4 weeks via Telematix email i cannot reply to.

They told me to pay R300 cancellation fee on the same date they sent the email if not that amount will change. I sent them an email asking for an explanation of their blatant exploitation and asked them to call me since they're not email efficient. I am still waiting for a call explaining the nonsense.

They continued to debit my account for a car i no longer have and a service i made clear i no longer needed. i disputed it and will continue to do so including ignoring any bills directed to me Telematix without direct communication. i don't need this drama in my life.
