Cant bother to fix info and keep up to date with payments even with proof of payments!

I wish there was a 0 out of 5 rating for Ampath! I am going to use another lab next time for my tests. I keep getting bills and bills and bills and I keep paying and paying. And yet I got an email that I have been handed over - for an amount paid TWO months ago already. And then I suddenly got another account and I paid that too. I keep sending ALL proof of payments to the proofofpayment email address EVERY time. I am deaf, I cannot call Ampath, and I have already sent the proof of payment emails! Oh and I need to mention - I used to be on my mothers medical aid until 7 years ago. 7 years ago I went over onto my own medical aid but my mother's ID kept being used on accounts and her email address to send the bills to. It has been such a hassle and struggle to simply change the details. It took months for someone at Ampath to actually understand that the details need to be changed.
