R 5604.90 for twenty minutes at Alberlito.

Netcare Alberlito. On the 6th of May I emailed ronnel.naidoo@netcare asking the following: "Hi Ronnel, Please can you let me know what this account was for? And what the total outstanding amount is? Kind regards and thank you." So that I could settle the Alberlito account in full. The day after Devenhree replies on the 7th of May sending me an account of R 1871.60 and I ask for a discount which she then offered and I paid it. So the account is paid in full, as I asked in my email specifically what the outstanding amount is. So I assumed... Now today 9 May I receive another account from Ronnel saying I still owe another R 2012.00 to the hospital for the Doctor. This after I asked for the full outstanding amount in my first email. Dear Netcare is there any other accounts or bills you want to add to my account whilst you are at it? Apparantly yes, Lancet has just called saying I owe them R 1721.20. So 20 minutes at Alberlito costs you a total of R 5604.90! So you are now billing me R 1871.60 plus R 2012.10 plus R 1721.20 for Lancet, which totals R 5604.90 for twenty minutes at Alberlito. I do not have a medical aid. And I will not pay nearly R 6000 for 20 minutes at Alberlito. I asked for the outstanding account, one got send and I paid it. I will not pay one more cent to you. I find it devious that you respond in this way after I asked for the full outstanding balance. If you don't have medical aid and would like to spend R 5604.90 for 20 minutes in a hospital, you know where to go.
