Wonga

I had a rough month in December and I could not pay for my installment. Wonga customer service contacted me mid january 2020 and I asked the consultant to schedule a debit order for the 25th of January and they did not debit my account. Mid February 2020 received another call from their attorney cause apparently my account has been handed over and I asked the consultant to schedule a debit order for the 25th of February and they have not debited my account again. My worry is that this account is accumulating interest every month and im also worries about my credit record. Is wonga going to debit my account when it's R3000.00 were by I owe them R630.00.
