Complain about ER Consulting

Good day. My name is Zakithi Pearl mokoena. I have a problem with the company mentioned above. I had my mother as my beneficiary under my medical aid scheme. Unfortunately she passed on this year January 18 due to cancer. The according to my knowledge I have paid what ever was short when I took her to the hospital. And yet I am getting a message from ER Consulting stating that I am oeing them R2500 and yet I went ot my medical scheme they said they paid everything and yet I received a message saying that they have put my name under bad debt. I sent hem an email asking them to allow me to pay R200 a month until I settle their account last month I send them an email asking them for bank details. I had no response. And this month I got a message that I now have a bad debt rocords so I paid R200 this month but still no records.. Pls verify
