poor and **** communication and information

I went to Pathcare for some blood that was requested by my dr. They informed the medical aid (Discovery) will only pay R100 and that the remaining amount of R2563.32 is for my own account. The admin lady told me that this need to be paid and then the account is settled, not at any stage was I told that there will be more to be paid at a later stage and this morning I recieved an email that state I have to pay another R2112.18. I phoned the accounts department and asked them what the rest is for and the consultant said that it was for screening tests, which show on the Final Report(attached) and where i was told that this is the amount to be paid by myself before they will be able to take the blood samples. The the consultant told me that I had to read the document and I told him the administrator told me that this is the final amount for all blood work that needs to be done.
