Paul Hoepfl & Kriek - Shocking Business Ethics

Good Day

On the 10th of May 2019 my daughter went in for surgery on her broken ankle. After surgery Paul Hoepfl & Kriek based in Hillcrest KZN who supply Orthotics & prosthetics supp**** my daughter with a moon boot which she needed to wear for six weeks which was billed to my medical aid. I have just received a phone call from their accounts lady in March 2021 informing me that medical aid did not pay in full. I informed this very rude lady that I was not aware of this and why had I not been contacted in 2019 where I could of claimed off my Gap Cover to be told by her that she wasn't working for them and she does not know why. I then told her I suggest she write off this amount of R3000.00 as I would not be paying it due to there incompetence. She has since handed my daughter who is 21 years of age over to Lexmed. I refuse to pay this amount based on principle as to how may other people is this done to. Please note as of to date 18 June 2021 I have yet to receive an Invoice or statement of account for this moon boot which was supp**** in May 2019 and Lexmed are charging my daughter interest for an amount she should not be liable for and all I get from Lexmed are weekly sms's threatening to blacklist my daughter for a Companies incompetence. My question is how do we as individuals except this and how can we blacklist these companies.
