Outstanding bill for 6 months and back and forth between bonitas and lancet lab with no resolution

I have a bill for a pcr test done in hospital on the 24th November 2025. This bill was not paid. There has been back and forth between myself and bonitas where bonitas stated that it was not submitted by lancet for authorisation and when I tell lancet then it is stated that it was submitted as per lab form. Can bonitas contact lancet to resolve this or can the 2 parties and myself get on a call to resolve this? I even escalated this to lancet management
