Disgusting fees added on by Woolworths and MBD Attorneys

I have a Woolworth credit card which has an attorney took over in 2020 due to non payment - because of lockdown. My initial debt was R2600. Attorney has informed me (within the last year) that my balance is now R6000. I called in last week and my balance is now R9000. How do you justify this woolworths! It's blady disgusting. I want to settle the debt but I refuse to pay these fees that have been added on to a value of R7000 even though I paid the attorney on time every month since 2020. I suggest someone from your finance department calls me to sort this out, you will not receive another cent from me until this has been queried!!!
