Passing the buck

Yesterday I received a correspondence from GEMS about my SON"S admission at life poortview and they said that the hospital did not update the level of care and today life poortview sent me correspondence from GEMS that said I was liable for the cost of the level of care during my son, s admission I think they are playing mind games with me and I am stressed about what they are doing my son had severe depression hence he was admitted and GEMS seems not to want to settle the bill by them saying that the hospital did not update meanwhile the hospital says they updated the level of care and the length of stay can hellopeter please assist me to get to the truth

My son is Ntsako mabaso was admitted in h July 2019
