Poor Customer Service

I have been a loyal customer of ABSA Bank, Homeloans for over 14 years. Losing my job in 2019 brought the business relationship we had to a horrible end. My house was sold through HelpUSell within ABSA Homeloans in 2022. Until in early 2023. When I was contacted by two different ABSA Legal services personnel requesting me to make an outstanding payment on my Homeloans account. I gave an Affidavit to the first ABSA Legal Representative stating my current unemployment stance. No one has made me aware nor was I sent an amount owing to ABSA before and after my former house was sold. I got emails and phone messages recently informing me that I owe an undisclosed amount of money to my Homeloan account. Can someone explain the sudden payment arrangement I am expected to make. I am unemployed with no source of income. I lost my house and did not receive a cent from its purchase or profit. All the money was paid to ABSA by the buyer. Why am I asked to make a payment when I do not even know the amount to be paid. I find the cold treatment from ABSA unacceptable and unprofessional.
