Bad Service / Incompetence

Monday / Tuesday the 13/14th of July about an account overdue for a 180 days for R3500. The medical aid did not cover it. It is my responsibility which I acknowledge, and say I shall pay in full at month end the 31st of July. On Friday I call to see the dentist and get an appointment for Saturday and get reminded about the amount outstanding which I say someone had phone me about and that I made an arrangement AND an appointment is booked for Saturday. Saturday I get called to say the dr is not available and they apologise and book it for Monday. On my appointment on Monday I am told I cannot receive treatment because the amount is outstanding? At the practice I cannot be seen after an arrangement has been made. I am saying NO, I made an arrangement, nothing was said again and the bookings were made with no further issue about the account, how can they say this to me now? No one says this to me when I make the appointment that I will not be treated if this is not paid. SO I am not aware of an unpaid bill, I am made aware, I want to pay. I have never had outstanding amounts in 12 years and I get refused treatment!!! Full email sent to [Email Removed]
