Inconvenient and unprofessional service received

When being admitted into Flora Clinic for a procedure on 30.10.2023 i receives pre-authorisation from Unity Health for a CT scan and radiology before arriving. I lost my husband two months ago in a farm attack which I was also injured. I am now recovering in the Flora Clinic Highcare unit with pain medication as the procedure I am here for was done yesterday.. i am now expected to pay for the CT scan and x-rays based on letter head with no invoice or details via eft saying I will be receiving invoices later. This is very inconvenient and I feel very unprofessional, saying the are independent from the hospital
