Extremely dissatisfied customer

This complaint is regarding a declined Health cash plan policy My spouse was hospitalized from the 12 Aug to the 28th August, I logged a claim and was declined due to according to the assessor he was only in hospital for the 27th and 28th which does not meet the 48 hour criteria, however I sent through all documents and doctor/nurse notes, a letter confirming the operation procedure was done on the 13th and his transfer letter from the 1 hospital to the next and back again, which was almost 40 pages. How is this only 1 days worth of notes, I was then asked to send proof of being admitted on the 12th which I sent only to get a response "Unfortunately, we could not process the claim as no required supporting documents were received", everytime you need to send something a new email need to be sent and this seems to delay this process, this is quite frustrating.
