Poor service

My debit order date is set to be 25th. In June they didn’t debit. I got a call earlier July consultant was very rude and I explained I didn’t reverse any debit order yet she insisted to say I did then said they can debit my account as there is money then hanged the phone, did they debit no. They kept calling me sending me whatsapp messages I asked for account number and made the transfer. After I made the payment didn’t they debit my account🤷🏿♀️ they did and did a debicheck debit order which they did not send me the mandate to sign. I called and received a very unsatisfactory response and treatment worse been sent from one pillar to another did they refund? No. They I get the debicheck mandates endorsed by me NO I didn’t the response I got “Cartrack can debit your account whenever they want as long they can find money in your account” did I acknowledge that, NO I agreed for a debit order on the 25th. Please help me selove this complaint and can I be provided the debicheck mandates approved by me. The first consultant I spoke to was Boitumelo was not even interested to understand my concerns
