Unauthorised taking of money

Payment agreement in place with Autopage which is being adhered to. Twice this year they have tried to debit a total of R2700 from my bank account despite this, which has in addition incurred bank fees for failed debits. I logged my concern with the helpdesk twice. On the first occasion they responded with a closed ticket saying that the account was in arrears. Second occasion they responded once again with a closed ticket asking for more information. I received a mail from Sandy Adams informing me that my account would be handed over. I asked for clarity but have not had a single repsonse or acknowledgment. It just seems as if they do not listen and do not care about what their customers have to say.
