Disgusting Service

I joined debt busters in 2019 and was paying them every month until covid hit and I could not keep up with payments they then automatically cancelled their service without notifying me so I paid my creditors myself. I am now in the process of removing the debt review flag and now they tell me that I owe them an amount of R1449.00 "aftercare fees" which as the team leader explained was service fees for the four months I could not make payment during covid. What were they servicing when there was no payment made? I am extremely disappointed in the service and treatment that debt busters offers their clients, you are supposed to help people with financial difficulties not take the little they have.
