Unprofessional behavior

On Thursday the 18th of March I went to Alberton union hospital because my sister was sick, when I went to xray I was helped by a lady named Kelly I explained to her that I didn't have the funds to do the test she than told me it was okay that I can pay it monthly... When I went to pick up the result that night a guy helped me and refused to give me the results saying that I need to pay, I explained him that Kelly had helped me and she said I could pay this off monthly as I do not have any money at the moment. The next morning I got a call from Kelly telling me that I was suppose to pay for it and she did not tell me that I can pay this off... She was a big liar... How can I pay for results that I do not have... How unprofessional is the people working for this company... It's so sad that when you sick and people tend to frustrate you and speak lies... If I was suppose to pay upfront why was the money not taken immediately?
