Pathetic service from Lancet

I was admitted to hospital in March of this year. The dr requested tests and some of them was marked for isolation as per drs request. However Lancet wants to claim this money from me. They submitted it to my medical aid and my medical aid says that the portion they are billing for is for the hospital and the patient is not liable and the medical aid is also not paying for it. So from March we have been struggling to get this removed from the bill so that i can settle the difference. The hospital billing manager has no priority or pride in her work and keeps sending me from pillar to post. Lancets accounts department is even worse. I have been emailing and spoke to a few people on the phone but no joy. I am super tired of useless people that has jobs while so many other people is unemployed. I NEED THIS SORTED ASAP
