Shady Accountancy

Pathcare sends a statement for an unpaid amount. This does not make sense as this was supposed to be covered by medical aid - so we ask for the request completed by the doctor as well as their account. What we do receive is a letter of demand for payment. So we pay the amount. Then we find out that Medical aid has paid most of the account. We ask for a refund but they say there is no refund - the account is not in credit. (Various requests) I submit proof of payment again and demand that a senior person be involved. Yes they received the amount but the apportioned part of the payment to another account. - They did not request permission, nor did they advise me. They refuse to return my payment. Now we take up the second account with medical aid. Pathcare is submitting accounts for payments, using the wrong ICD10 codes - hence the claims being repudiated. Medical aid processes the newly submitted accounts and makes a payment . We ask for a detailed statement - which we do not get and once again, they demand payment for the incorrect amount. I have asked for contact details of a manager from day one - and they refuse to oblige - management hiding away?
