Misleading

My fiancé (Ntsikelelo Runeyi) receive a call from one of their agent Nonka and he wanted them to assist him with increasing his credit score as he has finished paying his DMC account. I (Nokuthula Mgunculo) was then interested in the same service from them so I provided the agent with my details using the same cellphone. This company wrongly transferred both our names for debt review service and none of us is under debt review nor struggling with our finances. Last month they deducted R1439.00 each from both our accounts. We tried calling them to cancel but yet we are receiving messages from them stating that they will be deducting again R1439.00 and I don't know for what. Nonka said the company is unable to refund our money and she promised to process debit order cancellation on both accounts but yet we receive messages from them. I have emailed their "case manager" department last month and this month, no response till today. I have cancelled their debit order on my side but I still got messages from them claiming that the debit order was unsuccessful meaning that they tried to debit this month again.
