Discovery Insure Refuses to pay agreed cash settlement

We recently had some property damage due to a burst pipe that the municipality failed to tend to in a timely manner. We lodged a claim with our home insurer Discovery. Their appointed contractor came to evaluate the damage and provide the quote to discovery for the repairs. The following day the appointed assessor came to evaluate the damage. A few days later we received the Aol from Discovery insure with the claim amount of 92k. We signed and sent the Aol back within minutes. A few days later we received email confirmations that the amounts had been paid into said bank account and will reflect within 72 hours. 48 hours later we receive a new Aol stating a new figure of 23k. The Discovery consultant just said "this is the correct Aol". The previous payments of 92k had been reversed. On Discovery's Aol document it states and i quote "Kindly note that this agreement of loss becomes binding only once accepted by Discovery insure by wither counter-signature or payment" Discovery reversed the payment and will now refuse to go any further with the claim until we sign the new Aol for the lesser amount. I would like to add that on the claim tracker it states that our claim is now closed and complete yet we have received no payment whatsoever. When we call into the Discovery hotline we are told that they will not abide to the original Aol and we must take it further.
