No co-operation fro Lancet Laboratories, only harassment

I was admitted to hospital with a deadly fungal infection called Candida Auris. Prior to my admission and during my hospital admission, blood samples were taken by Lancet Laboratories on request by my specialist. Theses blood samples were sent for analysis to identify the infection which I had in my knee as a result of a prior knee replacement. During my month long stay in the hospital, I did not have access to my laptop and could only communicate via my phone. The claims by Lancet Laboratories were sent directly to my medical aid for payment. During my first week in the hospital, I received an SMS that part of the Lancet account had not been paid by my Medical Aid. Shortly afterwards, I received a telephone call from the Lancet call centre reminding me that my account had an outstanding balance. I informed the call centre operator that I was in hospital without access to my laptop and would attend to the short payment as soon as I got out of hospital. Lancet Laboratories continued to send me an SMS on a daily basis and I received calls from the call centre (every time a different operator) almost on a daily basis. I had to repeat the story of me being in hospital and no access to my laptop, every time I received the calls. On 3 April 2019, I lost the fight against the fungal infection and had to have my leg amputated above the knee. This was a very emotional time for me, but still the harassment by Lancet Laboratories continued almost on a daily basis. On 12 April 2019, I was discharged from hospital. At home I logged into my medical aid web site and extracted my monthly member statement. On examination of the statement, I found that the majority of the claims that were not paid because the Medical Aid (Bonitas) had requested additional information from Lancet Laboratories. The non payment code was "Pathology test method required from the pathologist". The next call from the call centre was within the next day or two. I explained to the call centre operator what was stated on my monthly statement and requested them to obtain the information required by the Medical Aid and re-submit their claim. Since 14 April 2019 up until today 7 May 2019, I have not been successful in getting Lancet Laboratories to supply the information to my Medical Aid or to myself. The SMS and phone calls continue. In desperation, I went to Lancet Laboratories rooms at the Pretoria East Hospital, where I was a patient and spoke to the senior Registered Nurse Suster Carina Talbot. She was extremely helpful and tried via their internal Lancet system to explain what the Medical Aid was looking for. Even this did not seem to have had any effect as I still received SMS and phone calls from the call centre. On Wednesday 1 May 2019, I wrote an e-mail to Lancet Laboratories explaining that I require the results of the "Pathology test method required from the pathologist" so that I can re-submit the Lancet claim. I have only received acknowledgement of my e-mail but no response to my request. I do not know where to go from here and that is the reason for my review. I am getting no co-operation from Lancet Laboratories, only harassment for the outstanding amounts on my account. Thank you
