Lancet Makes mistake and holds us responsible

I pay for a medical aid so that I don't have to pay for blood tests. These clowns linked my account to the incorrect medical and the claim was rejected. After acknowledging their mistake they still made it my problem to resolve the issue. My medical aid was willing to still pay for the claim even though the tests were done more than a year ago so I decided to call Lancet to make sure they had the correct details before they resubmit the claim again and to my surprise these clowns linked my account to the incorrect medical for a second time. I made 100% sure that they rectified my details on their system and ask them to resubmit the claim. A month later they sent me an email to say they are not going to submit the claim and I need to pay the outstanding R599.99 balance. Now my account has been handed over to Strauss Daly attorneys and I have been warned that I need to pay the account this month or make a payment plan. After reading multiple reviews about Lancet I now see that my case is only one of many. Lancet's administration is of poor standard and they do not take responsibility for errors. We trust them with important and personal information and expect that they handle their clients in a professional and medical caring way but instead they have proven to just be another money greedy organization that can't even take responsibility for their own mistakes. I specifically make sure my doctor does not send my blood sample to them ever again and advise anyone who reads this to do the same.
